Nope, no backups happening at the time.
Anyone other ideas?

Hi John -
Yes, at my former workplace, we had a couple of different instances
where we experienced severe crashing problems on G4-based machines.
Prior to using a G4 Xserve, we were using a dual-G4 tower as our
MySQL and Intranet server, and as we ramped up MySQL usage, the hard
crashing got to where it was nearly every morning. Finally traced
it to our backup process, Retrospect, accessing files while MySQL
was trying to access them. Specifically excluding MySQL's data
directory from your backup process is a must. Excluding temp and
log dirs is also probably a good idea. We were already dumping out
data out to another directory daily, but didn't realize that the
simultaneous access would be such a problem. This was with MySQL
3.23 and later 4.0, and OS 10.1 through 10.2 I think.
When we moved to a G4 Xserve (serving MySQL and our Intranet), we
again had horrible crashing problems. Weird, like none I'd ever
seen, where the OS basically just entered a slow spiral of death
that led to it either rebooting on its own or us noticing the
problem first and hard-resetting it. Apps would stop opening, cli
processes would no longer run, running apps would slowly stop
responding. Traced it to a pair of Kingston RAM modules. Once
those were out, the machine righted itself and I believe continues
to serve data (though no longer MySQL) to this day. Weird I know
but I swear that was it. This was with MySQL 4.0 and (I think) OS
10.2 through 10.3.
HTH,
Dan

I've got an xserve running 10.3.9 and MySQL 4.0.27-max that is
restarting itself every 2-3 days. It appears that it is due to a
kernel panic, though I don't have direct access to the machine
(colocated) to verify when it occurs.
There are no crash.logs from MySQL, and watchdog and system.logs
show nothing. I have culled the following panic.log - can anyone
tell if MySQL is the cause of such?
Has anyone seen MySQL 4 crash on an Xserve (G4 specifically)? I
have tried two totally different servers, and the problems continue.
