From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6 Description of problem: This is a dual Opteron system with 8GB of memory. When running the 64 bit version of Sun JRE 1.5.0_05 (the latest at this time) with a heap of 6GB and the server VM, the system reproducibly kernel panics after a few minutes of running the JVM. I don't have a screen grab of the kernel panic, but it does mention the java process and SE linux, so those would be areas to look at. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Run a java server app with the -server option and -Xmx6144m -Xms6144m 2. Sit back for a few minutes 3. Watch the system kernel panic Actual Results: Kernel panic. Expected Results: Application running. Additional info:
A capture of the panic message would be very helpful. Is it in /var/log/messages? Also, the hardware here seems to be x86_64, not ia64?
Oh yes, x86_64 is correct. I checked /var/log/messages, but there are no panic messages in there. I've photographed the screen with my cameraphone and attached it to the ticket, I hope this helps. This time around, I wasn't even running a Java app, I was just grepping /var/log/messages for the word "panic" -- which caused it to panic. :)

Seems updating to the -22 kernel made a difference. No crashing since I upgraded. I'll close this ticket for now.
