I'll have to see about getting that. I think I mentioned that I'm not
physically located with the equipment.
Are the interface speeds all the same? LAVC was built for 10 Mbps Ethernet,
and while running it faster should be ok, running mixed speeds may create more
congestion than the protocol is comfortable with.
Good point.
Is there any way to show packet loss counts? Can you run DECnet, and if you
put a significant load on DECnet connections, do the DECnet counters show any
errors?
The counters I've checked via NCP and LANCP show no errors, no
collisions, no overruns.

It might be better to hard set the Linux simh host system's port to 10Mbit

DEC hardware...
I just asked my colleague to try forcing that.
And I take that back about turning on throttling not making a
difference. It has made a difference---the system is no longer coming
all the way up. I'm not sure why, as the reasons long ago scrolled away
because of all of the "lost connection" messages. I didn't think to
record them.
Thanks!
