The only dropped process I'm getting is an occasional httpd drop on signal 10 or 11 (to my recollection). >> When it powers back up, the CMOS clock is still correct, but the >> system clock is off by (apparently) random amounts -- usually less >> than 12 hours. > > I don't understand this.

I don't understand it either. :) If I type "date" after the event, it still shows the correct time zone (PDT), but the clock will be off. I am getting "Invalid Time" warnings on EVERY startup, even when the clock is dead-on. Since this started, I've activated ntpd to try to correct the clock issue, but suspect I'm treating a symptom rather than the cause. It is possible that I misremember the CMOS-issue. When I become aware that it has restarted itself, I'll check the "date," then "fastboot" and check the CMOS clock in the BIOS setup console during startup. It is usually pretty close then, even though the immediately-previous "date" showed the time being several hours off. >> Running 4.6-Release. TYAN S2462 board with dual AMD 1666MHz >> processors.

I was running 4.3, then 4.5 on a similar board, but with 1GHz Athlons. No problems (till the room overheated one day, then I lost a hard drive). > Are you getting messages about IDE problems? Yes. When the machine starts back up from "the event," the file system reports multiple problems. It's almost as if someone just pulled the plug and then plugged it back in. I'm not getting any other file system related errors. SHM To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
