Trouble with 2 Unibusses and 2 UDA50s

Since installing a second uba, second uda50, and 4 more ra81's on one
of our 4.2BSD VAX 750's, we have had major problems restoring files.
Symptoms include crashes during restores and restored files being
corrupted.  (The dump tapes are OK; they work fine on a different
system.)  Also the DEUNA, which got moved to the 2nd Unibus, is now
flakey, too, occasionally becoming very sluggish or ceasing to operate
at all.

Is there anyone out there running 4.2 with such a configuration,
especially 2 uda50's?  If so, I'd like to hear from them or from anyone
else with ideas.  If you run such a system, what versions of
vaxuba/uda.c, vax/autoconf.c, and vaxmba/mt.c are you running?
