I am hoping someone can shed some light on the problem we are having here on 
our bridged network. 

We have a 3COM IB/2000 Ver. 3.1 ether-to-ether lan bridge. It seperates an 
ethernet that has a variety of hosts. On one side of the bridge, the e-net
has two parallel processors, a VAX cluster, and a Sun workstation that acts
as a gateway to a Cray XMP. The other side of the bridge has another VAX
cluster on its e-net. Users access the hosts from points on both sides of
the bridge. Protocols are TCP/IP, DEC, and XNS. There is no filtering being
done on the bridge. It is there just as a monitoring point and a means to
seperate the ethernet if necessary.

The problem is, the 3COM bridge intermittently resets itself (reboots). There
are no error conditions or anything out of the ordinary that we can see. We
have replaced the bridge with another 3COM IB/2000 and it still continues. It
will occur several times in a one or two day period, then may not happen again
for a week or so. It may happen any time of the day or night. We have contacted
3COM two different times about 4 or 5 weeks ago and they hadn't heard of this
happening before and were supposed to get back in touch with us. We are still
waiting.

Has anyone else had any similar experiences? Hopefully Bridge Communications
(3COM) is subscribed to this.
