MEMORY CRD ERROR

Hello wizards. Can anyone help me with the following problem ?

Running Ultrix3.0 on vs3200 w/ two RA81s + RA80 + deqna + 2 dhv-s (not
in use). The computer is used mainly as an nfs server last connected
to a terminal server (not used a lot already).

We have a high rate of MEMORY CRD ERRORs. It started from the
installation (long ago!). A piece of error log is appended.

In the last two weeks we had some sudden crashes of the system getting
"04 ISP ERR" message on console (no panic() / core dump), the address
of crash is in _Xprotflt().

We are not sure that this problem is related to the memory errors but
it is logical - high rate of interrupts that make the stack larger and
larger until ... crash!!!

Digital technicians replaced the two X 8MB memory modules, the CPU and
the connector between CPU and memory - nothing helped.

Questions:
- Is there a way to core dump (remember that isp is high). Tried DEPOSIT PC -1
  C but it did not work).
- Anyone can give me a clue ?

----- a piece of log file (last message is first), outputted with uerf -R -----
                                                  uerf version 3.0-008 (88)
