Server 'freezing'

[Rob Brandt]

It's happened again.  It made it almost 5 days this time.  This
time, for the first time, while I'm sitting in front of it with
the screen not blanked out.  I could see that there were no errors
displayed before hand.  Every thing looks great, except of course
that it's totally frozen; no mouse movement or anything.

Nothing that I recognize as significant.

I'll see if I can find something.  This server boots initially to
OS9, so if your tiBook utility is for OSX it won't help me.  BUt
I'll do a search.  And if I don't find anything, I'll start trial
and error stuff.  There are 3 256 MB sticks in it, and I'll pull
one at a time to see if the seg fault continues.  And if that
yields no results, I'll still some RAM from another Mac that never
has problems and test with that.

I'll check it out.

Thanks
