Hi all,
We are running a new Centos-4 server, and it has kernel panicked on us 4
times in the last month. After the first kernel panic we hooked up a
serial console to the server and captured the output in order to have a
record of what happens. I've included the error messages from the last
time it locked up... but it doesn't really mean much to me. Anybody have
any ideas what might be causing this server lock up?
Server description:
-Dell PE1750 - dual 2.8Ghz Xeon (with Hyper Threading on) - 2GB DDR RAM
- Perc4-DI onboard RAID using 3 scsi drives in raid-5 configuration
-ext3 file system
-kernel-smp-2.6.9-5.0.3.EL
-mysql - from distribution
-2 postfix instances rebuilt with MySQL support
-amavisd-new
-clamav
-spamassassin
-rbldnsd
-bind
Here's the captured output from a serial console connected to the server
at time of fault.
Unable to handle kernel NULL pointer dereference at virtual address
