Just got back from Palm Desert. While away I had left 3 XP1000's,
a VAX and a DS10L running in the cluster. Owing to our annual winter
storms we had a several power outages here in Pebble Beach. After
the first outage the systems rebooted. There were apparently several
other outages and when I returned I noticed that all the power switches
on the XP1000's were dark. Not so on the VAX or DS10L. Depressing the
switches restored things to normal. Anybody expreience this with these
machines? Is this a known bug? AUTO_ACTION is set to RESTART.

My XP1000 systems seem to remember the power switch setting properly
(unlike my early edition PWS 500a[u], which did not). Sounds like a
mystery (unless your batteries are dead, or an NVRAM is fried, or
something like that).

Batteries are OK and NVRAM is fine and they have successfully rebooted
after a number of power outages. I think we can also rule out neutrinos
on probabilistic arguments. My guess is that power irregularities somehow
put it into a funny state and it shut down, maybe a surge.
