Jazz Team Server : Multiple Crashes each day
Hello,
we are running JTS Version 3.0.1.2 (RJF-I20111207-1350), free version for up to 10 developers.
I limited the Java Heap Size to 2 GB because 4 GB exclusive are not available. Additional RAM is already ordered and hopefully improves the situation. Back to the problem:
Tomcat crashes several times each day and writes core-, javacore- and snap files to the server directory. Unfortunately nobody in our team has experience in analyzing these files.
I added the last two javacore and snap files, and hope somebody can help us analyze the problem as it's impossible to work smoothly at the moment :-(
Here they are: http://dl.dropbox.com/u/4685125/dumpfiles.zip
And a status screenshot (sorry, partly german): http://dl.dropbox.com/u/4685125/Statuszusammenfassung%20-%20Serveradministration%20-%20Rational%20Jazz%20Team%20Server%20-%20Mozil_2012-04-18_18-24-19.png
Regards,
Andreas

The first thing you need to do is to get 4 gigabytes on your server ... 2 gigabytes just isn't sufficient.

Hello,
does nobody have a clue? Or is this the wrong subforum?
Is it possible to get official support? We have access to IBM Intranet, as some of us are students working for IBM.

Andreas, I took a look at your javacore, and it doesn't look like you were crashign due to out of memory. For some reason, you're hitting a crash in the JVM's JIT compiler. You can recognize this by the "GPF" event and the j9jit23.dll in the header info:
If this recurs, we'll need to look at whether there is a JVM fix available.
Thanks,
Scott

Hi Scott!
Thank you!
Unfortunately it's happening again
http://dl.dropbox.com/u/4685125/javacore.20120424.180042.2348.0003.zip
We helped ourselves by using a batch file which scans the tasklist for java.exe and in case of a crash (no process java.exe) it calls the server.startup.bat from the jazz installation. But this only considered as a workaround!
We'd really appreciate your help!
Regards
Andreas
