Need Ultrix V2.0 info

[Anders Ardo]

  We have tried using a MVAX-II running Ultrix 2.0 as major NFS-fileserver
for our SUN 3/50s. It worked fine as long as the load was light, but when
a number of machines (say 3 - 5) used the NFS it crashed. The crash was hard
with either "Segmentation fault" or "Protection fault" in one of the
FS daemons. After the initial crash the system would play jo-jo going up
and crashing almost imediately again.
  Our configuration is:
  MVAX-II, 9 MB, DEQUNA, RD53 (RQDX3), RA81, TK-50 and a TS-11 tape controler.
  SUNs all run SUN Os 3.4

  DEC is working on the problem, they have switched ALL hardware with no luck
and the software support say's "Hmm hard problem, we'll look into it".

  If anyone have any hints as to what is wrong I would like to hear from you.

[ There are a number of problems with NFS under Ultrix v2.0.
I know that at least some of them (perhaps the worst of them)
are avoided by not running /etc/biod.  -- Art Z. ]
