I
have been told that the DEQNAs had problems and would lock up or
experience
other reliability issues. DEQNAs are not supported after about VMS
5.4/5.5,
which is why I need a DELQA. I am not sure what the minimum VMS
version
is
for DELQA though.
DEQNAs never worked right, even after 12 revisions. That's why they
were dumped and the LQA was created. For moderate loads a QNA should be
ok, though. The big problem was that they weren't good enough for Local
Area VAXcluster use, which was a big thing in those days. I don't think
DECnet was thrilled with them either but DECnet was more tolerant of
misbehavior.
I don't remember DEQNAs being dumped by the PDP11 operating systems.

They work fine under RSX11. We used them on a dual network flight data
processing system (electronic flight strips) for about 10 years.
