Roland Thanks for the ideas, Roland (and Tamouh)! I forgot about the possibility of power issues. I do have an Antec power supply, 500W, which certainly doesn't mean it isn't the problem, but it _ought_ to be able handle this system...

The voltage on the 12V lines seems pretty bad, and especially so on the -5V line. Should I trust the sensors and think about a new PSU? In the meantime, I'll write to a file, and see if it records a dip in power before the next reboot. -- Ned Ruggeri ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

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 12 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.

If you suspect rTorrent, try switching it off for a couple of days. If you have the cpufreq(4) driver in your kernel, you can activate powerd(8) in rc.conf. That will reduce the CPU speed it the system is idling, keeping everything cooler.

I'm not a big AMD user, but I would guess given the list of features on the motherboard's site that you have some sort of hardware supported CPU frequency control. I would hunt around your BIOS, see if you can enable that functionality, and see if that solves the problem. I will say that your MB and memory vendors sound like small 3rd party groups, and I've faced a lot of issues with those types of vendors; that's why I stick with select ASUS MBs, and Corsair or similar memory vendors. -Garrett ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
