System hung over night
When I woke up this morning at 5:30 to head to the airport, I heard my
system fan going at full speed. I tried to log in to the locked system,
but no response. I had to power cycle. Looking back in messages, the
last messages were right after 4am:
# grep "Jul 15 04" messages

And then nothing until the restart. Any recommendations on where to dig
to guess at what caused this?
Last night I had done an update and had rebooted the system, so it was a
fresh boot, but with all my processes running.
thanks
