I notice that my system booted mysteriously during the night.  How can I find
out what happened?  Are system crashes logged somewhere?

I happened to have top running at the time of the crash.  The last screen looked
like this:

Looks like cron was generating its nightly e-mails of system status, but apart
from that, I don't see anything wrong.

Any ideas?
