Are the fans running?  Has someone actually looked?  Not after
rebooting, but before rebooting?

Have you used chkrootkit to make sure you haven't been rooted?

Have you installed logsentry?

What kind of security do you have installed on the system?

It could be a network problem... but it doesn't have to be.

How about a cron job to send you the temperature of the RaQ every
quarter-hour?

The easy way is to create a file with the following contents at
/etc/cron.quarter-hourly/mailtemp (without the snipmarks, of course):

<snip>
#!/bin/sh
echo "  " > ~/tempfile
grep temperature /proc/cpuinfo >> ~/tempfile
/usr/sbin/sendmail jlasman@xxxxxxxxxxxxx < ~/tempfile
</snip>

chown it root:root, and chmod it 700

Not only will this send you the temperature every quarter-hour, it'll
also let you know if the RaQ is working while you can't reach it.  If it
still sends you email while you can't reach it, then that's a repeatable
symptom.

If it doesn't send you email while you can't reach it, but has some
saved up when you finally reboot it, that's another symptom.

I'd sure start this way.
