Kernel: vanilla 2.4.19-pre8 at the moment.  I recompiled after adding
Steven Tweedie's latest ext3 patch the other night, but that's it.
I've been following the 2.4.19-pre kernels "religiously", but never
mix in *any* other patches.  While I don't have any actual oops output
from previous kernels, I think this has been around in every
2.4.19-pre.  (I've been having trouble for longer than that, but my
last round--see link below--at least *appeared* different.)

Stuff That Runs: vanilla.  syslog-ng, bind 9.2.1, gated, portmap,
ypserv, xinted automount, cron, rpc.mountd, ypbind, rpc.nfsd, Apache
(hardly ever touched), Backup Exec agent, postgres 7.2.1 (only hit by
Apache).

Webtrends runs early every morning.  A bunch of other machines rcp log
files to it between midnight and 04:00.  I've had oopsen while
webtrends is running and while it's not running.  I've had them just
when there are rsh/rcp sessions from a couple different machines at
the same time.  I've even had them when the machine is (as far as I
could predict) completely idle.


If you have suggestions for stuff to run (or not)--whatever--I'll be
glad to try it.  I can start going backwards kernel-wise, if you want
me to try to pin a starting point for the problem.

I have a lot more patience than kernel hacking skill, so I'll do what
I can, and you do your thing. :-)

A steak dinner and a case of your favorite if you fix it.  I'm
*really* tired of getting paged and driving in to the office in the
wee hours of the morning to hit the freaking reset button.  I do
preemptive reboots some evenings so I can control it, but it may still
croak a couple hours later.  (I'd love an APC MasterSwitch right now,
but I can do a *lot* of driving and switch-flipping for $600.)
