I have a mix of fairly stock Redhat 5.2 and 6.0 apache web servers that I
recently moved to 2.2.13 kernels. Prior to 2.2.13 I used 2.2.12. With
both versions I have been experiencing lockups after a few days of
uptime. Unfortunately, the boxes lock up completely and require a power
cycle, so I'm not left with much to debug these lockups with, no console
messages, nothing in the log files, etc. Any suggestions as to what I
might be able to do to track this down would be appreciated. Below is more
info about these servers.
Thanks,
David
None of the servers seem to be very overloaded, vmstat show what I would
think to be normal usage. (Correct me if I'm wrong)
procs memory swap io system

The hardware in each server is similar.
PPro 200 or PII 350 or greater ( no smp)
256 M ram or greater
Buslogic 958
UW scsi 9 gig
3Com 905 or 900
About the only thing special I do with the kernel config is compile in
support for serial consoles.
