Yup...that was us.

That is exactly the behavior that we noticed.  You can have either
DEQNA running and still have other things going on, but not both.
When we were running both DEQNAs everything would run find for about
20 minutes, and then WHAM!--anything attempting to use the disk would
get hung. 

We experienced the same problem using 4.3BSD.  We eventually fell back
to Ultrix 1.2, and the problem did not surface again.

We now have a cisco router to do the job for us, and our MicroVAX II 
is running Mt Xinu again.
