kernel panics on a ProLiant 800 server

[Chris Purcell]

I have an older Compaq ProLiant 800 server running RH73.   This server ran
flawlessly for 2 years, with an uptime of about 300 days before it crashed
the other day with a kernel panic.   I rebooted and then installed some
errata updates using apt including upgrading the kernel to the latest
version (2.4.28 I believe).   Ever since the day of the crash, the server
has been going down once a day with kernel panics.   This must be a
hardware problem since the server is pretty old and it ran perfect for
over 300 days straight before this.   I tried replacing the Smart Array
531 RAID controller with a newer Smart Array 3200 controller and also
replaced the NIC but its still crashing with kernel panics.   There is
absolutely nothing in the logs that I can see.   How can I troubleshoot
this?   Should I just replace the old server?   The server is out of
warranty, otherwise I would call Compaq/HP for some hardware
troubleshooting.

Thanks,
Chris
