Help!

We just installed a new repeater and are having connections dropouts.
We have a MicroVAXII and Vaxstation 2000 in a Local Area Vax Cluster.
The dropouts appear to occur randomly 4-10 times a day/night.
Basically, the Vaxstation is losing it's connection to the MicroVAX.

The repeater repeats signals from our gateway and MicroVAX
which are on the thick backbone, to twisted pair lines coming out
of the repeater.  The Vaxstation is connected to the repeater
via twisted pair and a TP-THIN transceiver.  The cable lengths
are relatively short so I don't think that is the problem.

Anybody had any luck fixing this kind of problem?  The
repeater is a 12-port Plexcomm AUI-TP repeater if it's
any help.  Operator network messages list below...

Thanks in advance,
