Thanks to all who replied, including Dr. Thomas Blinn, Brian Staab,
Alan Rollow, Juan Ramon, Charles Ballowe, Jenny Butler, and any others
that continue to come in.
I neglected to mention this was a dual processor ES40 in my posting.
The good Dr. Blinn said:

He's preaching to the choir on the support contract issue! The system
ended up going down 5 times over the weekend, even after the power
off reboot. I ended up coming in last night, did a cluster power
down, rebooted each node as the other (2 booted as 1 and 1 booted
as 2) and everything has been okay since (except that node 2 is
now running on suspected bad hardware).
Alan Rollow offered:
That it was a machine check points strongly at a hardware
problem. Your contract would probably have gotten you a
version of WEBES/CA that had analysis rules for the
system. If you have that installed, it may be able
to offer a clue. Having the WEBES/CA kit is sufficient
to use it; analysis doesn't require a license.
I'll persue this further to see if it tells me which cpu failed,
I just happen to have a couple of spares :-) and I could swap
the bad/suspect one out at our next *scheduled* outage.
Thanks to everybody that replied, and, not intended to slight
anybody, but WOW, aren't the two individuals quoted above sharp!
Thanks. Jeff

Subject: System panics
Help! I was under a Silver support contract for years (until new upper
management decided not to renew it in September--don't get me started on
THAT subject) and now I've had 2 system panics within 36 hours. Can anybody
shed any light on what may be wrong (i.e. some piece of hardware about to
die)? This is one node of a 2 node cluster, 5.1a, pk3. Here's a portion of
/var/adm/messages:

Alternatively, if anybody know how to use kdbx and could tell me what to
look for with it, that would help also--I've got crash dump files. Thanks.
