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

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.

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

Cheers,
Geoff

Thanks for the reply.

Now running with 6 GB physical / 4 GB Java Heap.
Hope that helps!

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:
1TISIGINFO     Dump Event "gpf" (00002000) received

If this recurs, we'll need to look at whether there is a JVM fix available.

Thanks,

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

Once again:
http://dl.dropbox.com/u/4685125/javacore.20120425.122111.1544.0003.zip

This time, clearly the JIT component again.
Can this be turned off without tremendous performance loss?
Shall we try another VM?

Is it possible to get any help on this topic? Or at least some advice, what we could try?
