Re: Server hanging

[Stephen Samuel <samuel@bcgreen.com>]

Are there any interesting messages in /var/log/messages?

This sounds to me like the symptom one gets when the disk or disk
controller locks up on IDE (yes, I know you're running SCSI, but do
you have an IDE CD in the box, or eomething?)  It still leaves me
wondering if the machine has hardware problems.  How long have you
been allowed to leave the box running to see if the problem goes
away??

One thing I'd suggest is opening a window doing a 'tail -f /var/log/messages'
If you're lucky you'll read complaints while they're still in the cashe and
before the OS tries to write them out to disk.
