You also may be running out of CLIST space for TTY output -- we sure did.
A way to improve on that (though not fix it) is to reduce the max packet size
for that interface;  we set ours at ... 256, I think.
(Of course doing this you drastically increase network overhead, but it's
better than crashing or running out of terminal character buffers)

Also, you might look at an open connection with TRPT to see how frequently
you re-transmit packets -- one bug fix that came over the net a while ago
left us retransmitting packets several times before they even got out of
the machine via slow links (e.g. 9.6kb serial line or IMP connections).
If you are resending a lot, we might have some fixes that would help.
