I'd like to thank everyone for their comments and offer current status:
It seems according to memtest (http://reality.sgi.com/
cbrady_denver/memtest86/) I do have some bad memory. I had originally
thought of this, and used the VA Linux burn-in software
(ftp://ftp.varesearch.com/pub/software/Cerberus) to test (which
returned no error results). I guess don't trust www.crucial.com for
memory. Should have stuck to mushkin.
Unfortunately I'll be in Washington DC for a week starting today, so
won't have a chance to get my hands-on for further debugging until
then.
Thanks for pointing out memtest. Hopefully I can isolate at least 1
good chip so I can do my benchmarks/testing. If anybody else has done
large (~ process > 150MB, 4 hour+ run-time) Mentor Calibre jobs on
Linux, please let me know about success, failures, and caveats.
Thanks,
--Greg
FYI, during the heavy load I introduced today I got 4 Oops too!
