Given this stack trace snippet
Caused by: java.net.SocketException:
Software caused connection abort:
socket write error at
java.net.SocketOutputStream.socketWrite0(Native
Method)
I tried to answer the following questions:
What code is throwing this exception? (JVM?/Tomcat?/My code?)
What causes this exception to be thrown?
Regarding #1:
Sun's JVM source doesn't contain this exact message, but I think the text Software caused connection abort: socket write error is from the native implementation of SocketOutputStream:
private native void socketWrite0(FileDescriptor fd, byte[] b, int off,
int len) throws IOException;
Regarding #2
My guess is that it is caused when the client has terminated the connection, before getting the full response (e.g. sent a request, but before getting the full response, it got closed / terminated / offline)
Questions:
Are the above assumptions correct (#1 and #2)?
Can this be diffrentiated from the situation: "could not write to the client, due to a network error on the server side"? or would that render the same error message?
And most important: Is there an official document (e.g from Sun) stating the above?
I need to have a proof that this stack trace is the socket client's "fault", and there is nothing that the server could have done to avoid it. (except catching the exception, or using a non Sun JVM SocketOutputStream, though both don't really avoid the fact the client has terminated)
This error can occur when the local network system aborts a
connection, such as when WinSock closes an established connection
after data retransmission fails (receiver never acknowledges data sent
on a datastream socket).
See this MSDN article. See also Some information about 'Software caused connection abort'.
The java.net.SocketException is thrown when there is an error creating or accessing a socket (such as TCP). This usually can be caused when the server has terminated the connection (without properly closing it), so before getting the full response. In most cases this can be caused either by the timeout issue (e.g. the response takes too much time or server is overloaded with the requests), or the client sent the SYN, but it didn't receive ACK (acknowledgment of the connection termination). For timeout issues, you can consider increasing the timeout value.
The Socket Exception usually comes with the specified detail message about the issue.
Example of detailed messages:
Software caused connection abort: recv failed.
The error indicates an attempt to send the message and the connection has been aborted by your server. If this happened while connecting to the database, this can be related to using not compatible Connector/J JDBC driver.
Possible solution: Make sure you've proper libraries/drivers in your CLASSPATH.
Software caused connection abort: connect.
This can happen when there is a problem to connect to the remote. For example due to virus-checker rejecting the remote mail requests.
Possible solution: Check Virus scan service whether it's blocking the port for the outgoing requests for connections.
Software caused connection abort: socket write error.
Possible solution: Make sure you're writing the correct length of bytes to the stream. So double check what you're sending. See this thread.
Connection reset by peer: socket write error / Connection aborted by peer: socket write error
The application did not check whether keep-alive connection had been timed out on the server side.
Possible solution: Ensure that the HttpClient is non-null before reading from the connection.E13222_01
Connection reset by peer.
The connection has been terminated by the peer (server).
Connection reset.
The connection has been either terminated by the client or closed by the server end of the connection due to request with the request.
See: What's causing my java.net.SocketException: Connection reset?
I have seen this most often when a corporate firewall on a workstation/laptop gets in the way, it kills the connection.
eg. I have a server process and a client process on the same machine. The server is listening on all interfaces (0.0.0.0) and the client attempts a connection to the public/home interface (note not the loopback interface 127.0.0.1).
If the machine is has its network disconnected (eg wifi turned off) then the connection is formed. If the machine is connected to the corporate network (directly or vpn) then the connection is formed.
However, if the machine is connected to a public wifi (or home network) then the firewall kicks in an kills the connection. In this situation connecting the client to the loopback interface works fine, just not to the home/public interface.
Hope this helps.
To prove which component fails I would monitor the TCP/IP communication using wireshark and look who is actaully closing the port, also timeouts could be relevant.
For anyone using simple Client Server programms and getting this error, it is a problem of unclosed (or closed to early) Input or Output Streams.
Have you checked the Tomcat source code and the JVM source ? That may give you more help.
I think your general thinking is good. I would expect a ConnectException in the scenario that you couldn't connect. The above looks very like it's client-driven.
I was facing the same issue.
Commonly This kind of error occurs due to client has closed its connection and server still trying to write on that client.
So make sure that your client has its connection open until server done with its outputstream.
And one more thing, Don`t forgot to close input and output stream.
Hope this helps.
And if still facing issue than brief your problem here in details.

This error happened to me while testing my soap service with SoapUI client, basically I was trying to get a very big message (>500kb) and SoapUI closed the connection by timeout.
On SoapUI go to:
File-->Preferences--Socket Timeout(ms)
...and put a large value, such as 180000 (3 minutes), this won't be the perfect fix for your issue because the file is in fact to large, but at least you will have a response.
Closed connection in another client
In my case, the error was:
java.net.SocketException: Software caused connection abort: recv failed
It was received in eclipse while debugging a java application accessing a H2 database. The source of the error was that I had initially opened the database with SQuirreL to check manually for integrity. I did use the flag to enable multiple connections to the same DB (i.e. AUTO_SERVER=TRUE), so there was no problem connecting to the DB from java.
The error appeared when, after a while --it is a long java process-- I decided to close SQuirreL to free resources. It appears as if SQuirreL were the one "owning" the DB server instance and that it was shut down with the SQuirreL connection.
Restarting the Java application did not yield the error again.

In the situation explained below, client side will throw such an exception:
The server is asked to authenticate client certificate, but the client provides a certificate which Extended Key Usage doesn't support client auth, so the server doesn't accept the client's certificate, and then it closes the connection.
My server was throwing this exception in the pass 2 days and I solved it by moving the disconnecting function with:
outputStream.close();
inputStream.close();
Client.close();
To the end of the listing thread.
if it will helped anyone.
In my case, I developped the client and the server side, and I have the exception :
Cause : error marshalling arguments; nested exception is:
java.net.SocketException: Software caused connection abort: socket
write error
when classes in client and server are different. I don't download server's classes (Interfaces) on the client, I juste add same files in the project.
But the path must be exactly the same.
For example, on the server project I have java\rmi\services packages with some serviceInterface and implementations, I have to create the same package on the client project. If I change it by java/rmi/server/services for example, I get the above exception.
Same exception if the interface version is different between client and server (even with an empty row added inadvertently ... I think rmi makes a sort of hash of classes to check version ... I don't know...
If it could help ...
I was facing the same problem with wireMock while mocking the rest API calls.
Earlier I was defining the server like this:
WireMockServer wireMockServer = null;
But it should be defined like as shown below:

And most important: Is there an official document (e.g from Sun) stating the above?
I need to have a proof that this stack trace is the socket client's "fault", and there is nothing that the server could have done to avoid it. (except catching the exception, or using a non Sun JVM SocketOutputStream, though both don't really avoid the fact the client has terminated)
This error can occur when the local network system aborts a
connection, such as when WinSock closes an established connection
after data retransmission fails (receiver never acknowledges data sent
on a datastream socket).
See this MSDN article. See also Some information about 'Software caused connection abort'.
The java.net.SocketException is thrown when there is an error creating or accessing a socket (such as TCP). This usually can be caused when the server has terminated the connection (without properly closing it), so before getting the full response. In most cases this can be caused either by the timeout issue (e.g. the response takes too much time or server is overloaded with the requests), or the client sent the SYN, but it didn't receive ACK (acknowledgment of the connection termination). For timeout issues, you can consider increasing the timeout value.
The Socket Exception usually comes with the specified detail message about the issue.
Example of detailed messages:
Software caused connection abort: recv failed.
The error indicates an attempt to send the message and the connection has been aborted by your server. If this happened while connecting to the database, this can be related to using not compatible Connector/J JDBC driver.
Possible solution: Make sure you've proper libraries/drivers in your CLASSPATH.
Software caused connection abort: connect.
This can happen when there is a problem to connect to the remote. For example due to virus-checker rejecting the remote mail requests.
Possible solution: Check Virus scan service whether it's blocking the port for the outgoing requests for connections.
Software caused connection abort: socket write error.
Possible solution: Make sure you're writing the correct length of bytes to the stream. So double check what you're sending. See this thread.
Connection reset by peer: socket write error / Connection aborted by peer: socket write error
The application did not check whether keep-alive connection had been timed out on the server side.
Possible solution: Ensure that the HttpClient is non-null before reading from the connection.E13222_01
Connection reset by peer.
The connection has been terminated by the peer (server).
Connection reset.
The connection has been either terminated by the client or closed by the server end of the connection due to request with the request.
See: What's causing my java.net.SocketException: Connection reset?
I have seen this most often when a corporate firewall on a workstation/laptop gets in the way, it kills the connection.
eg. I have a server process and a client process on the same machine. The server is listening on all interfaces (0.0.0.0) and the client attempts a connection to the public/home interface (note not the loopback interface 127.0.0.1).
If the machine is has its network disconnected (eg wifi turned off) then the connection is formed. If the machine is connected to the corporate network (directly or vpn) then the connection is formed.
However, if the machine is connected to a public wifi (or home network) then the firewall kicks in an kills the connection. In this situation connecting the client to the loopback interface works fine, just not to the home/public interface.
Hope this helps.
To prove which component fails I would monitor the TCP/IP communication using wireshark and look who is actaully closing the port, also timeouts could be relevant.
For anyone using simple Client Server programms and getting this error, it is a problem of unclosed (or closed to early) Input or Output Streams.
Have you checked the Tomcat source code and the JVM source ? That may give you more help.
I think your general thinking is good. I would expect a ConnectException in the scenario that you couldn't connect. The above looks very like it's client-driven.
I was facing the same issue.
Commonly This kind of error occurs due to client has closed its connection and server still trying to write on that client.
So make sure that your client has its connection open until server done with its outputstream.
And one more thing, Don`t forgot to close input and output stream.
Hope this helps.
And if still facing issue than brief your problem here in details.

This error happened to me while testing my soap service with SoapUI client, basically I was trying to get a very big message (>500kb) and SoapUI closed the connection by timeout.
On SoapUI go to:
File-->Preferences--Socket Timeout(ms)
...and put a large value, such as 180000 (3 minutes), this won't be the perfect fix for your issue because the file is in fact to large, but at least you will have a response.
Closed connection in another client
In my case, the error was:
java.net.SocketException: Software caused connection abort: recv failed
It was received in eclipse while debugging a java application accessing a H2 database. The source of the error was that I had initially opened the database with SQuirreL to check manually for integrity. I did use the flag to enable multiple connections to the same DB (i.e. AUTO_SERVER=TRUE), so there was no problem connecting to the DB from java.
The error appeared when, after a while --it is a long java process-- I decided to close SQuirreL to free resources. It appears as if SQuirreL were the one "owning" the DB server instance and that it was shut down with the SQuirreL connection.
Restarting the Java application did not yield the error again.

In the situation explained below, client side will throw such an exception:
The server is asked to authenticate client certificate, but the client provides a certificate which Extended Key Usage doesn't support client auth, so the server doesn't accept the client's certificate, and then it closes the connection.
My server was throwing this exception in the pass 2 days and I solved it by moving the disconnecting function with:
outputStream.close();
inputStream.close();
Client.close();
To the end of the listing thread.
if it will helped anyone.
In my case, I developped the client and the server side, and I have the exception :
Cause : error marshalling arguments; nested exception is:
java.net.SocketException: Software caused connection abort: socket
write error
when classes in client and server are different. I don't download server's classes (Interfaces) on the client, I juste add same files in the project.
But the path must be exactly the same.
For example, on the server project I have java\rmi\services packages with some serviceInterface and implementations, I have to create the same package on the client project. If I change it by java/rmi/server/services for example, I get the above exception.
Same exception if the interface version is different between client and server (even with an empty row added inadvertently ... I think rmi makes a sort of hash of classes to check version ... I don't know...
If it could help ...
I was facing the same problem with wireMock while mocking the rest API calls.
Earlier I was defining the server like this:
WireMockServer wireMockServer = null;
But it should be defined like as shown below:

line being a string and ins being a BufferedReader
ins = new BufferedReader(new InputStreamReader(_sock.getInputStream()));
_sock being
Socket _sock = null;
_sock = serv_sock.accept();
This happends on my Server java and not on my client java...
Also, this happends when I dont send anything for a little while
-----EDIT------
I tried it again;
First it went 40 minutes of doing nothing and it still worked,
then I waited 40 minutes again and this time it didn't work.
It seems to be kind of random..
I can't figure out what's causing it.
The files I have are
* [client.java], [chat.java], [vlc.java]
* [server.java], [chat.java], [vlc.java]
the vlc files are the same in both although chat is different
(since I havn't done Threads in both client and server yet)
Here's the code;
SERVER
server.java: pastebin.com/GH8ShcGp
chat.java : pastebin.com/iaL23kSb
vlc.java : pastebin.com/9kyrbh5q
CLIENT
client.java: pastebin.com/HDK450Jg
chat.java : pastebin.com/CfHrEUkE
vlc.java : pastebin.com/SfZgYy58
I think it's a window/network thing.
Someone who please can help me fix this??
I couldn't get your exact problem to replicate on my own computer using your code and localhost-connections, but after reading about "BufferedReader.readLine() throwing java.net.SocketException: Software caused connection abort: recv failed" in several different pages, I believe this is related to your network. The connection seems to be terminated due to TCP timeout or data corrupted in the transmission.
If this happens over localhost-connections (server and client in same computer), it could be a faulty memory, otherwise you might have a broken nic, router or cable somewhere along the line. If you're using wireless, they can be pretty unreliable.
This error occurs exactly due to problem in network. It comes when connection with your database failed and and application is unable to retrieve the required data. The problem may be in your connection wire or with the modem. Try changing them. Otherwise check your database access in sql developer etc if its working fine, there could be a problem in transaction timeout.
There are two possibilities:
The database is down, or
The database server's IP address duplicates an existing server's IP address on the network
Given this stack trace snippet
Caused by: java.net.SocketException:
Software caused connection abort:
socket write error at
java.net.SocketOutputStream.socketWrite0(Native
Method)
I tried to answer the following questions:
What code is throwing this exception? (JVM?/Tomcat?/My code?)
What causes this exception to be thrown?
Regarding #1:
Sun's JVM source doesn't contain this exact message, but I think the text Software caused connection abort: socket write error is from the native implementation of SocketOutputStream:
private native void socketWrite0(FileDescriptor fd, byte[] b, int off,
int len) throws IOException;
Regarding #2
My guess is that it is caused when the client has terminated the connection, before getting the full response (e.g. sent a request, but before getting the full response, it got closed / terminated / offline)
Questions:
Are the above assumptions correct (#1 and #2)?
Can this be diffrentiated from the situation: "could not write to the client, due to a network error on the server side"? or would that render the same error message?
And most important: Is there an official document (e.g from Sun) stating the above?
