Yes, I can ssh in when it's up and running fine. No, looking at the
system.log (or system.log.0.bz, etc) doesn't help.

Right, ssh shouldn't respond when it crashes. Can you ssh in when

will show what happened when it hung, even if you're not around.

SSH doesn't work (no auth into the box when it crashes). From what
I've seen, my best guess is that Directory Services just totally
lock up. And as far as tons of AFP traffic, this tends to happen
on the weekends when one or maybe two people are here. Or at night
when no-one is here. I come in in the morning and find it hung.

Hi David,
Taking a stab at this here. If the crashes are that consistent, a
launchd job that restarts the box every 48 hours would provide a
band-aid. Hopefully you don't have to resort to that. Have you
ssh'd into that machine to see what's going on upon crash time?
Maybe something will show there. SSH in and then run this command:
tail -f /var/log/system.log
That might show you exactly what was going on when the crash
occurs. I'd be suspect of 2GB of RAM if you were throwing a ton of
AFP traffic at it or the like, but I see that you're saying it
runs perfectly until crash time.

Hi Guys,
We've run into a recurring problem where our OD Master totally
freezes up. All authentication into the machine stops working.
The only way to get the machine useable again is to restart it
(either hard power off or if I'm lucky, the XLOM card still
responds and I can restart it that way). I've found similar
threads from May of '08 (see below), but nothing more recently.
Have any of you run into this and come up with a satisfactory
resolution?
We're running 10.5.8 on a 2.0 GHz (x2) Quad-core Xserve with 2 GB
of Apple-supplied RAM. The machine runs perfectly until freezing
and there are no errors in the system logs that look suspicious.
At this point, I'm planning on having the machine restart once or
twice a week, as that seems to be often enough to stave off the
problems (we can generally get about two weeks before it freezes
up again).
