Re: Tracking Down Intermittent Kernel Panics

[Erich Schroeder <erich@museum.state.il.us>]

Only an anectodote, but I have a server that was giving me problems a 
while back. Every 30-40 days it would freeze up with some final records in 
/var/log/messages about seek failures. I was afraid that the SCSI 
controller or disk was going bad. It finally turned out that the UPS was 
fading, and was not giving enough power sometimes. Switched that out, and 
I'm good again.
