George,
Been there. In Brookfield (CT), under certain circumstances, when someone
would use the copier (not on the same circuit), the Novell server would go
down.
Here, we have all new wiring directly from the fuse box with really good
UPS's in between.
Thanks,
Carl

Since we must have by now exhausted all the normal causes of such
errors, maybe we should recommend
a) a visual inspection of the systems, to see if there are any pinsize
holes, or paint flaking off or so
b) the installation of a surveilance camera, to check if the SegFaults
are synchronous with any visible phenomenon (sparks, Cerenkow
radiation,
etc.)
c) moving the systems to the basement ?
There's a story in a book I once read where a computer system crashed every
morning around the same time. No one could figure it out. Finally, the head
of IS goes down to the computer room at the expected time. In walks a
maintenance man who comes in, opens the cabinet for the computer, and plugs
a floor polisher into a spare outlet in the cabinet. When the maintenance
man activates the polisher, boom, the system crashed.
When asked by his boss what the problem was, he told him it was a buffer
problem.

I used to have a Novell server that would mysteriously reboot every few
days. In my case, the server was on the same circuit as a laser printer, and
both were plugged into a Haworth cubicle outlet. Periodically, load was too
much and it would causes a server reboot. We brought in another circuit NOT
on the inadequate cubicle wiring system, and the problem went away.
