I am making load test for my web application, and I set the connect timeout and response timeout to be 20 seconds, and sometimes I am getting exceptions like:
Non HTTP response code: java.net.SocketTimeoutException: Non HTTP response message: Read timed out
I get the above exception in JMeter test result, and there are no errors thrown in my application, and no stacktrace available to trace the exception.
I want to discover the cause of the message: is the app waiting for something to process, or slow SQL, or hung thread, or application is refusing connections because maxed out?
How can I find why this exception is thrown, and how can I fix it?
I would recommend you improve debugging activities (in jMeter) in the following way:
try to add debug postprocessor to your http sampler
launch log viewer (jMeter log viewer before any http
sampler(-s)/script(-s) execution
probably this could help you to figure out why you're facing socket timeout.
Hope this helps you.

I am using apache JMeter version 5.5.
I am trying to run the sample test with more than 500 users. The test runs up to 200 users without any error after that start throwing list of below errors
Non HTTP response code: org.apache.http.conn.HttpHostConnectException Non HTTP response code: org.apache.http.conn.ConnectTimeoutException Non HTTP response code: java.net.SocketTimeoutException
please refer the image for the error details
errors are like this:
case 1:Time out error
case 2: Read Time out error
I have tried the below solutions:
1 enable and check of keep-alive button
2 setting the time outs up to 100000 milliseconds
how to overcome this errors?
Is errors from JMeter script or Server side ?
The errors are from the server side. By default JMeter waits for response forever, however there could be timeouts which are set on JVM or OS level.
You can try specifying explicit larger timeouts under "Advanced" tab of the HTTP Request sampler. If you have > 1 HTTP Request samplers and want to apply the timeouts to all of them - go for HTTP Request Defaults
I'm using IntelliJ IDEA to implement the Spring Guide for consuming REST services
https://spring.io/guides/gs/consuming-rest/
When I run the Application class I receive the following error
Exception in thread "main" org.springframework.web.client.ResourceAccessException:
I/O error on GET request for "https://gturnquist-quoters.cfapps.io/api/random":
gturnquist-quoters.cfapps.io;
nested exception is
java.net.UnknownHostException: gturnquist-quoters.cfapps.io
The URL itself (https://gturnquist-quoters.cfapps.io/api/random) opens fine in a browser and my HTTP Proxy settings in IntelliJ can connect to the site without any issues. Why would an UnknownHostException be thrown here?
Hey I know this is a bit late, but here is what I had to do to resolve this issue. Even if you are using system proxies, for whatever reason, using this type of GET request requires you to build out a proxy to use in the call, like so.

Jmeter I keep getting: 'java.net.ConnectException: Connection timed out: connect' ?
I have created a load test which tests a specific url at 200 users
when running the load test for x1 iteration i keep seem to be getting: Connection timed outs?
I have made the following changes listed here: https://msdn.microsoft.com/en-us/library/aa560610(v=bts.20).aspx
But the issue is still there:

You most probably don't have access to the target host from where you test.
Did you configure proxy as your web browser is probably configured
http://jmeter.apache.org/usermanual/get-started.html#proxy_server
But if failure is partial, then you server might be overloaded and rejecting some requests.
My expectation is that "problematic" requests are simply not able to finish in 20 seconds (most probably you have modified Connect timeout and set this value in HTTP Request or HTTP Request Defaults)
20 seconds looks like a long response time to me so your finding indicates application under test performance problem.
Going forward if you would like to see more "human readable" message in the results file switch to Duration Assertion instead of setting timeouts on protocol level
See How to Use JMeter Assertions in Three Easy Steps article for more information on conditionally failing JMeter requests.
Please check client configuration from where you are running your tests. It might be like your client system is not able to handle 200 threads. Do the test iteration wise means try with 10, 50 , 70 and so on. Check from which iteration onwards you are getting the error. It is also advisable not to include the listeners during load testing.
Please check the best practices for load testing using jmeter.

I'm using Soap UI 4.6.0 to hit a WCF web service, and when I have really large message payloads, I'm seeing the following error:
Error getting response; java.net.SocketException: Connection reset
The WCF service has around 10 methods, each with progressively larger inputs (eg, 10 int properties, 50 int properties, 100 int properties, etc). This works with the smaller messages, but as they get around 2000-3000 int properties, the error occurs.
The call appears to succeed on the server side, and with this coming from java, I'm assuming I'm butting up against some size limitation/configuration in the client. Is this something I can tweak within Soap UI, the java runtime, or elsewhere?
For me the trick that worked was adding below entry in SoapUI-5.2.0.vmoptions file (it can be found in the bin directory of installa
-Dsoapui.https.protocols=SSLv3,TLSv1.2
Normally a connection reset means that one of the underlying servers timed out waiting for data from another server/application and it reset the connection.
You should try out the suggestions #kroonwijk gave it'll tell you which server is causing the reset and what is causing the server to reset the connection.
Also see What's causing my java.net.SocketException: Connection reset?
If above solutions won't work for you then try this:
Close SoapUI
Go to SoapUi directory for example: C:\Program Files\SmartBear\SoapUI-5.3.0\
Rename directory "jre" to "jre.ignore"
Done. Open SoapUi and it should work now.
I have a few web services on a Weblogic 10 server. Each of these is part of a larger system. Running locally and on our qa environment the system works flawless, replies fast, and as expected. Everything looks to be okay.
Before going into production we're going to stress test the system, thus see how much load we can have before reply time becomes to large. When testing the web services (e.g. using front end or SOAPUI) we hit a certain load (e.g. to many replies per sec or something like that, I'm not sure what exactly triggers the system to fail) we get the error listed below. I haven't got the slightest clue as to why. Seconds later the system replies flawless again, so I'm guessing that it has something to do with the number of requests...
Any ideas or hints is much appreciated! I'm lost here, so please - anything will help.
We're running: Weblogic 10.3.2, Spring 2.5.6 (for architectural reasons we cannot upgrade), Spring-WS 1.5.9 (for architectural reasons we cannot upgrade) and Stripes 1.5.4

By digging BEA-101017 I found a little info about the from the Weblogic error dok - although this doesn't help me:
Error: [context] Root cause of ServletException.
Description: [context] Root cause of ServletException, which the Web
application container caught while servicing the request.
Cause: The Web application container caught an unexpected exception.
Action: Check the exception for the exact error message.
Assuming that the web service from your example doesn't access other web services (and therefore the above trace corresponds to your web service sending the response):
It seems that your web service, via SAAJ, is trying to write to a disconnected (or otherwise unavailable) socket. An usual cause for this is that the client has disconnected while waiting for the server reply.
I'd suggest to:
Check if your client was waiting for too long before receiving the response, that could have caused it to disconnect.
Check if the operating system might be having issues allocating sockets. Use 'netstat' or other monitoring tool (like TCPView on Windows) to check how many sockets are open (most operating system impose limits on the number of sockets allowed per user or globally).
Ensure there are absolutely no network errors during your tests (shouldn't be the case if you are testing on localhost, but otherwise you need to ensure your network devices (routers, switches, other computers) are not dropping connections or packets. Perhaps this is happening when traffic load is high.
Make sure you have no threading conflicts that could cause your web service to use or close other requests' sockets (this would be a rare situation especially if you are using Spring).
Check this thread Official reasons for "Software caused connection abort: socket write error" and other possible causes of "Software caused connection abort" (note that the issue could be specific to your application server and operating system).
Hope that helps.
After debugging a lot I found out that the problem happened due to DB2 issues - we hit a corner of our database, which triggered an internal stack overflow, which then probagated to the Dao and onwards to the SOAP-part (only making it harder to detect due to Spring JDBC templates in the Dao).
A long story short and the issue was an uncaught exception, which by Spring-WS resulted in a "SaajSoapMessageException". The hint came from "Software caused connection abort: socket write error", but happened on the WS side (not client nor the communication between client/server).
Hint: Surround your database with try/catch and catch Exception thus being able to find the exact exception thrown. In my case it threw a DB2 exception ("SQLCode -1218") and this is normally used when you run out of resources (e.g. data source connections). I my case it was the SQL which DB2 didn't like - and really didn't like under load. I can't explain it, but it has to do with DB2s own internal resources - gah, go figure! :)
Thank you jjmontes, for hints and pointers, but it was not the problem in this case.
