Hello,
I had a RHEL4 system crash a day or two ago. First RedHat system that
I've ever seen completely hung, requiring me to hard power cycle it.
Felt like my Windows days. But then it happened yesterday as well.
So something is wrong with this server.
It's fully patched (up2date), and is a Dell 2850. I captured the
/var/log/messages right before it panicked and here's the logs:

Jun 4 21:26:42 myhost kernel: <0>Fatal exception: panic in 5 seconds
So I'm not sure what to make of that. I noticed one process name in
there (bbtest-net) which is part of my BigBrother monitoring system.
But that's been running OK for years, and hasn't been changed
recently. Not sure where else to look. Could this be a hardware
(memory?) problem?
