It seems that you are getting hard memory write faults
on the stack.
Maybe something is hanging up the Q-bus, or you have failing memory. If
you have diagnostics, running a memory test for a while may get you
somewhere. Otherwise, I'd look into trying to pinpoint the problem by
removing memory modules and see if the system becomes more stable
(assuming you have multiple memory cards, of course).

I do have multiple memory modules, there are two in the chassis. I have spare modules,
but they aren't the same, so I am not sure they will work in the system.
I did pull and replace the CPU, Memory and VCB02 modules, but the result is the same. The
system did work fine recently, so I assume that the CSR/Vectors are ok on the cards. I
don't have the manuals for everything, but maybe bitsavers does.
I don't have any spare grant continuity cards...will this cause me trouble if I just
pull a ramcard out and have nothing in its slot? I seem to remember that you couldn't
have an open slot between cards, unless you had a grant card in there...
Is there a standard VMS memory test I can run in conversational mode?
