What is 'monitoring'??

What addresses are you getting errors on?

Should these be otherwise valid addresses?

The stack stuff should be OK, I'd do a "checkStack" and "memShow 1" to
see if vxWorks is sane before and after these obscure IRQs.

I have run a software-only EPICS database on the nitro-60 using NO
other VME hardware in the crate and it appeared to run OK.  The only
reason for alterations to the vxWorks kernel would be determined
entirely by the other hardware you wish to use in the crate.

I am not entirely sure, but I believe that the A16 area to be safe
as-shipped.  Your A24 and A32 regions probably require some hackery in
the sysLib.c file.
