[net.unix-wizards] Help! I'm trapped

jim (04/29/83)

My usually-faithful Vax 11/750, Beaver, has recently been crashing
about once a day with trap type 8.  They never happen in the same place
twice.  About the same time this started, we found some bad memory,
which we replaced, but we still get the traps.  All memory passes
disgnostics, as does the processor.  I haven't called DEC field service
yet, but if the machine passes diagnostics, I don't know what they
could possibly do for me.  Has anyone seen this before, and can you
help?

A trap type 8 is a segmentation fault in the kernel.  I don't know
if you have changed the kernel at all, but if you have then all
local changes should be looked at suspiciously.  We were getting
trap type 8 faults for a while and finally found an error in a
locally developed device driver.  I don't know if this has been any
help in the problem, but I thought it might be useful to hear from
someone who has had similar problems and resolved them.
