Perhaps you could help me with a problem that's occurred a few times with
the SGI O2 on my DPX400. Most of the time it runs without giving me any
grief at all. However, if there's ever any trouble with the local (or not
so local) network it starts to lose the place - there are communications
failures to the spectrometer (CCU, BSMS, that kind of stuff), and it will
take half an hour to shut down and twenty minutes to start up again. And
that of course does not sort the problem.
At the end of last week the main high speed line out of the city was down
and I had all sorts of bother. (Servers located _within_ the city were
absolutely fine.) With the patient help of Winston Belle in Coventry I
found the O2 was helpfully seeking some clock server on the other side of
the world just to keep the clock time right. However, even after we put a
stop to all that it was still sick. It remained peevish until that high
speed line came back up, when it flew along again as if nothing had
happened.
I can only presume it's feeling the network for something, but I can't
figure out what. This doesn't happen often, just as often as the network
goes down, but it's a real pain when it does. Has anyone else seen this?
Has anyone got a solution?
