Hello,

Here at Oklahoma State University, we have been using 6 Intel 286/310
systems running Xenix 3.0 & OpenNet (over ethernet) for about 6 months
now and we are having problems.  These machines are being used for under-
graduate class work (~150 student accounts) with all 8 of their RS-232
ports running at 9600 baud.  The problems seem to arise when we have
3 to 4 people loged on to each machine.  The students are given no
idea what machine they are loging onto.  Rather, we had expected OpenNet
to handle the load.  This however seems to be incorrect.

During the peak load times (day before an assignment is due :-),
one system will randomly lock up and take the entire system down (as
described below).  Typing on the console will do nothing.  However,
the other machines seem to continue to function as if nothing is wrong.
However, when the next student logs on wanting to access files (over
OpenNet) to the down machine, the machine they are loged onto halts,
locks up and becomes the next one to die.  This procedure goes on and
on until all 6 machines are dead as door-nails.

If the first death is caught in time, you can reboot that machine
and then things are fine for a time.  However, after about 30-50 minutes
the next machine in the sequence from the name server out will die.
Then the whole process starts over again.

Has anybody else who has these machines heard of something similar?

Is anyone at Intel reading this?  If so, we have OpenNet R1.0 (U1.0),
Xenix 286 3.0, 512K of memory, and one iSBC 188/48 per machine.

			Help!!!!!!!!!!!!!!!!

Please reply directly and thanks in advance,
