Since 3 days ago, our freeBSD box has automatically power-down-then-up 3
times. (This has happend only 3 times, all in the past 3 days.)

The symptom is neither of a 'reboot' command, nor a power button activation,
but a reset button activation (or someone pressing the power button twice,
or switching off and on the power point on the wall, which are publicly
accessible). The last 2 times during the boot i saw "... file system not
cleanly unmounted. rebooting automatically".

During all these reboots, i did not notice any power failure to my PC or the
office lighting. The freebsd box is in the same room, 20 meters away from
me.

Is there any software/hardware fault that can trigger a power-reset? How do
I confirm the cause? If it's a disgruntled employee, then how do i track her
down?
