Mystery crash

Hi

This morning on arrival at the office my AlphaStation 200 4/233 had
crashed and an attempt to reboot was made before noting if there was
any message on the console (<- flames courteously accepted).
(Running Digital UNIX V3.2D-1 (Rev. 41), Firmware revision: 5.0)

It is unlikely to have been a power glitch since nearby machines were
undisturbed.

The system would not reboot without a fsck fixing several problems on
the users disk first.

The system is working fine now but:

I have lost any sign of anything happening between ~15:30 and the crash
which happened after 22:20 when I did a login and normal(?) exit.

"Last" does not show any users logging on/off since 15:30 even though
there should have been several sessions logged.

Users had their .history files cleaned out (no entries or vanished).

Old mail messages (from several days ago to recent) got resent or
mangled/combined and resent to unrelated users on the system.

I think I have looked at all files under var/* with a mod date of
yesterday on and see no mention of any activity during the blanked out
time.

As stated above, everything is normal now but I worry. Does anybody
have any ideas what went wrong or where I might look? Do clocks ever
fail on these machines and if they do what might you see?

Thanks for any clues

Dave
