Bug 125837

Description of problem:
I'm running RedHat 9 fully patched (2.4.20-31.9smp) with mostly 
default settings.  In order to get consistent backups with dump(1), I 
take advantage of LVM snapshots (lvm-1.0.3-12).  I have nightly 
backups to a remote tapedrive, and disk-to-disk backups a few times 
during the day.  It works pretty well, usually.  But then there's the 
occasional kernel crash.  :(

The first time this happened, the server (astro) was under fairly 
high load, as a result of a memory-intensive program causing the 
machine to swap.  While that was going on, my 18:00 backups ran, and 
the LVM module gave an Oops, leaving the machine unusable.

I chalked it up a rare event due to the extreme load the machine was
experiencing (I think the load was above 10 at the time, and it was
using a full gig of swap), and went on with life.  But it just 
happened again, when nobody was on the server, during my 12:00 
backups.

Debugging kernel crashes is slightly beyond my skill level, but I 
wanted to report the problem.  I can provide additional information 
if needed.



Version-Release number of selected component (if applicable):
