It's possible, but we can't know one way or the other.  We suspect a
cron process interacting badly with another running process, but it's
impossible to prove.  The machine reboots before the offending process
can exit, so process accounting isn't giving us clues.

The machine does run a daemon process for a user, which prepares HTML
in response to requests from a CGI script (it's the back end to his
web site).  This is moving to another machine today, and I'll look
eagerly to see if the reboots follow it.

Is there any way to get more data on what's going on when the machine
reboots?  Any clues about the synching disks situation?
