Bug is already known about.

There is a bug in Ultrix 3.1 on the DECstation which causes it to drop packets;
Ray Lanza uncovered this bug in UEG a month or two ago during some
performance analysis.
Interesting enough, it is not in the ethernet driver....

This will be fixed in the next release, and then your DECstations should
be able to melt the wire, if your other end can keep up....

Thanks for reporting it in any case, though if you send a formal bug
report, it is much harder for Digital to forget, lose, or ignore
problems.  As these can be sent in electronically these days, (if you
don't require formal response), I don't think this is too very much to
ask...
