Right, ssh shouldn't respond when it crashes. Can you ssh in when it's up and running fine? Then tailing and looking at the system.log will show what happened when it hung, even if you're not around.

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.

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:

>>> 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?
