SunOS localhost 5.9 Generic_117171-07 sun4u sparc SUNW,Sun-Fire-880
This afternoon, this machine just rebooted, and I cannot find the why!

Following the reboot, all status lights on the v880 are normal, and
all disk drives are functioning.
There is no crash dump, and the only thing I can find in the logs
which indicate a glitch is in the /var/adm/messages file: the last
entry before the "new" boot-up entries is a "line" of ~308 NULL bytes.

I've run prtdiag and all temperatures, fans, etc. look Ok.
Things look correct from 'metastat'.

This unit has 3 power supplies which are plugged to UPS, so it wasn't
a glitch in power service coming to the machine, and if it's a power
supply the thing is supposed to be able to continue with two of them
functioning. And there's no indication of any problems (prtdiag) with
either of the three.

Anybody seen this sorta thing happen?
(Maybe there's some gremlin in the v880 and/or Solaris 9 that I've
missed.)

This sorta thing makes me nervous.
