[Info-vax] Old Reliable crashed

[Rich Jordan]

My 'Old Reliable" VAXstation 3100-30SPX crashed today.  Info:

VAX/VMS V6.2, with all 'class1/class2' equivalent updates of the
time.  Motif V1.2-5
32MB RAM
One internal disk (RZ25)
Two external disks (RZ25 data, RZ26-L system)

At the time of the crash I had 5 DECterms, calculator, and calendar
running.  The crash occurred when clicking on a DECterm to select it.
Below is the ANALYZE/CRASH SHOW CRASH summary.  If anyone can provide
a thought on what was unhappy it would be great; I've got some spare
components for it.

Since it was a machine check it was probably a hardware related
issue.  The system had been up since July 19th (we had a powerfail).

Sorry, but its been so many years since I had to try analyzing a crash
dump on anything and we're swamped...

And... my news service is being wonky at the same time Google Groups
is acting like Microsoft Windows and just not working so please
forgive any delay in responding.  Thanks
