Subject: Kernel Panics from FC4 Server
Date: Fri, 9 Jun 2006 14:23:32 -0700 [thread overview]
Message-ID: <d5d4185b0606091423w1b9a943fk786d2cabcdb6953e@mail.gmail.com> (raw)
Hello everyone.
We have some web servers in production running FC4, which are
exibiting intermittent crashes due to a kernel panic. The panics
occur at random, and can not be attributed to any one specific act.
Thanks to a serial console setup and conserver, I was able to get the
following output from the console:
Unable to handle kernel NULL pointer dereference at 0000000000000002 RIP:

This particular machine is a Dual Opteron 246 at 2GHz, with 2GB
physical ram, and 2 1GB swap partitions on the hard drive. We're
using the 64-bit edition of Fedora Core 4, with kernel
2.6.15-1.1831_FC4smp. More info is available upon request.
Does anyone have any ideas what could be causing this?
I'm not subscribed to LKML due to the volume, but I will try to
monitor any replies over the web. If possible, please CC me.
