Our SL6.2 KVM and nfs/backup server has been crashing frequently recently
(starting around Fri 13th - yikes!) with Kernel panic - Out of memory and no
killable processes. The server has 48GB ram, 2GB swap, only about 15GB
dedicated to VM guests. I've tried bumping up vm.min_free_kbytes to 262144 to
no avail. Nothing strange is getting written to the logs before the crash.
Happening with both 2.6.32-220.23.1 and 2.6.32-279.1.1.
Anyone else seeing this? Any other ideas? I've set a serial console log to
try to catch more information the next time it happens.
So I believe I've figured out what the issue was. I was hitting a kernel BUG
in the hidraw system (filed
https://bugzilla.redhat.com/show_bug.cgi?id=846047) which was triggering the
crashdump kernel and *that* was running out of memory. I just wasn't looking
back far enough in the console logs (starting from the bottom) to see the
original issue.
