If the system both shutdown *and* rebooted, I had the same
inexplicable thing happen to me many times. It began happening
to my Dell 8200 (hmm?) say, three months ago, and I
believe I solved the problem about 6 weeks ago.
There was some unknown fs fault in my /var slice. Just by sheer
chance, I watched my server abruptly powered down when something
[maybe] tried to write to /var/* and failed. At first I
thought it was bad memory; then, just-maybe, a bad drive.
(The drive is new, and 512MB of the DDR is also new.) I
also thought it was a heat problem, and that I needed another
fan. ... .
Long story short, I saved /var /<somewhere>, then found
something I couldn't remove. chflags did no good. Finally
I did a /bin/rm -rf /var. After I added it back, newfs'd it,
and copied back the stuff, no-more-spontaneous-and-random
reboots.

PS: it was fsck that couldn't fix the bad spot. The fault was
related to an inode allocation snafu. but i've never
hacked any fs code, so ....
