I am using apache 2.4 on fedora and when i am trying to open my page, it is showing completely blank. I checked the apache logs, there are many lines showing ([core:notice] [pid 1483] AH00052: child pid 1486 exit signal Segmentation fault (11)).
I have no idea what is causing this error and getting blank page is because of this only or not.
Thanks in advance
I saw this on a server configured to require client certificates to grant access to the site. The cause was an expired CRL, and installing a new CRL fixed the issue.
The reason becomes apparent by increasing the log level for the relevant vhost to info. By default it only logs error or worse, which only produces a cryptic message about failure to re-negotiate a handshake.

I've done another deploys and all was fine, but after finishing the app, I'm getting this error. And the page request keeps loading.
Do I need to configure something in "IAM"?

I've got new data using Stackdriver debug.
"message": "Stackdriver Debugger API has not been used in project
929024293238 before or it is disabled. Enable it by visiting
https://console.developers.google.com/apis/api/clouddebugger.googleapis.com/overview?project=929024293238
then retry. If you enabled this API recently, wait a few minutes for
the action to propagate to our systems and retry.",
Just a note if somebody else stumbles across this error: I had the same message in Google's App Engine dashboard popping up up to 60 times in a couple of minutes.
Enabling the Stackdriver Debugging API, as linked above, solved it. No more error logs (of that kind) were being produced. The weired thing is that the Stackdriver Debugging API should have been turned on by default for my standard environment.
The log wasn't very informative.
I change the application port from 8000 to 8080.
application.properties:
server.port=${PORT:8080}
Now the app is running fine.
A general exception occurred while trying to access CAS. Please notify your system administrator.
I am new to this topic, so I started from basic.
I followed step by step process from the following site
https://wiki.jasig.org/display/CASUM/Demo
when I finished step-8, everything was fine and I got similar kind of logs as mentioned in step-8, when I hit this url
http://sathishkumar:8080/servlets-examples/servlet/HelloWorldExample
I am getting "CAS is Unavailable
A general exception occurred while trying to access CAS. Please notify your system administrator" error.
I created certificate with sathishkumar as Common Name(CN) because it my computer name.
I am running it in windows
We are facing a weird issue where a similar configuration is yielding unexpected results for consecutive requests on Tomcat 7.0.54.
We have enabled the request dumper filter on Tomcat 7 and it shows that consecutive requests are missing the parameters.
Due to this our application is throwing a backend error and giving a bad user experience of not letting the user complete a transaction.
Did anyone face a similar issue on Tomcat 7 ?I can share more configuration files as required to help give more details on the issue.
Helpful pointers are greatly appreciated.

I am facing a peculiar issue while trying to SFTP a file from Windows to Unix server. The error "stack trace" is -
4: Failure

I have searched a lot on other forums but could not get to the root cause. I have observed one more thing - the file name, I am trying to SFTP, is *.xml when I change it to *.XML the SFTP is "successful". Very weird could not identify the issue. I am trying this using JSch Java API. But I have seen the same issue while trying the WinSCP front end.
It is common for OpenSSH SFTP server to return code 4 (Failure) for many different reasons, without giving any details.
You would have to check SFTP server log to find more.
Though the most usual cause is a lack of free disk or user quota space – Which can usually be identified by the file being created with zero size.
i was facing the same issue. was puzzled then i realized there was a space issue on the server folder. Please do check the server available space.
command: df path to the folder
I was facing the same issue. Please make sure that your SFTP service is running. And If it is already running then restarting this service should do the trick.
I had the same issue. Tried everything, turns out I had set the timeout to what I thought was 30s but it was actually 30ms. Changing it to 30000ms solved the issue.
session.setTimeout(30000);
I've seen this error and the cause in my case was, the uploaded file names weren't supported by the file system used by the SFTP server.
I encounter this error after a number of https requests. Anyone have any idea what could be the reason? It seens to be related to SSL. But previously it was working fine. I really don't understand what could have caused this issue

This is a standard annoying error you get sometimes in Java web apps. You get this error when requesting a URL and then either hitting stop in your browser or clicking away to another url. The app is complaining that it wasn't able to send you the complete response.
In my case this was happening when I generated an Excel or csv file on the server for local download (crash at HttpServletResponse getOutputStream().flush())
However it is related to the browser configuration, in my case Chrome 32 bits on Windows 7. Nothing on server side.
For 3 days I've investigated in depth my web application, looking for the cause of the problem, checked many apache librairies etc.
Then I tried to perform the same action from an another computer and finally from the same one with FireFox. No problem.
Finally I discovered that the cause was Chrome’s default Cache Size.
I changed it with -disk-cache-size-2147483648 (at the end of the shortcut's target) and problem disappeared.
I hope it can save time to someone.
A Java NIO Pipe is a one-way data connection between two threads. A Pipe has a source channel and a sink channel. You write data to the sink channel. This data can then be read from the source channel.
Now coming to the problem. Whenever sink channel is FULL (reads are NOT fast enough to leave some space in the buffer ), pipe is closed!!
So any writes coming after this point will fail.
