My system randomly reboots, usually in the evening. It is definitely

Try and install the mbmon port, and see if it works on your machine. If
so, start a cron job that appends mbmon output to a file say every 15
minutes. If it's a heat buildup issue in a monitored component, it
I wonder though. My machine usually doesn't need a day to heat up after
a cold start. An hour or so usually suffices.
Other causes could be a spike in the line voltage due to a large device
switching on or off nearby. Or an underrated power supply overloaded
through a cron job.
Also, check to see if your memory doesn't have any errors. That can
cause reboots from time to time if either the memory controller is bad,
or the memory itself is bad.
Also, this heat issue could be true for your hard drives. I've seen some
of my faster drives get up to 140 degrees F (before I bought fans for
them), then force the workstation to hard reboot. This was when I was
doing a lot of disk access with them, too, since normal idling didn't
head up the drives enough.
a. What's your Processor (speed, vendor)?
b. Who made your motherboard?
c. Who made your RAM?
Athlon X2 4200+ proc (2.2GHz, maybe?)
DFI nF4 infinity SLI motheboard
G.Skill RAM (2GB)
Antec True Power II (550W)
I'll use MemTest or somesuch to test my RAM latter today for errors.
The drives sit right infront of the air-intake fans for the system, so
there's a breeze that flows by them constantly. However, additional
cooling certainly might be necessary. Perhaps, it is possible that
rTorrent is doing a lot of reads and writes to the drive, stressing it,
which may be why the problem seems to have come up around the time I
started using rTorrent.
I think my plan will be so:
1.) Continue running mbmon until I get a restart, and then check to see if
there was a voltage drop (or, less likely, a heat spike).
2.) Then, run MemTest86+ for a day or so, checking for RAM problems.
I don't have a probe to measure the hard drive temps, but if 1&2 fail,
I'll arrange better cooling for the drives, I guess. If it's a driver
issue, is there any way to find it? I haven't installed any new hardware
recently, and hadn't had this problem until maybe a week ago.
Sorry to clog up the freeBSD listhost with (likely) a hardware issue. I
can move to another listhost if you guys think I should.
