Actually, it becomes more often today.  I must have experienced
more than several times in a worktime.   I may be better to check it
for a terminal machine, but not CPU server machine...

At first, I doubted power problem, because we use 100 V power for
designed 115 V power.   It usually does not cause problem.  However,
I experienced fail before when the switching power supply would be
poor.   In this time, 300W power supply is used.   The machine only has
a 1.6GHz Pen 4, 51MB memory, a CDROM, a floppy drive and a VGA card.

I tried slidac to make up the power from 100 to 115 V, but it did not solve
the problem either.

 From the file server's log, I know only it's link to file server hanged-up.
I've never been at front of our CPU server when it lost the link to the
file server.  So, I can see only lines of messages after new reboot on a
console of CPU/Auth server.

As Jim know, kernel level checking would exceed my ability, sorry...
If someone kindly contact me detailed, I may be able to try it.   Anyway,
It'd be better to use that machine for a terminal at first, and I'll do it later.
And I'm planing to parchase a new motherboard using dual Athron
for our CPU server.   Yes, I got a good news from a shop who can still sell
that kind of motherboard.
