Guess what, it waits 5 seconds then prints this: The alternate system clock has died! Reverting to ``pigs'' display. I don't know what the 'alternate system clock' is supposed to be but my guess is the CMOS battery ran out or something like that. I'm going to check that at the next available opportunity.

A reboot solved my problems -- while examining this phenomenon PostgreSQL came to a halt and wouldn't restart due to a lack of available shared memory, although ipcs(1) didn't show any active handles. Since I needed the database server, I had to reboot. I suspect something hardwarish though, I've never seen this kind of weird behaviour before. --Stijn -- The rain it raineth on the just And also on the unjust fella, But chiefly on the just, because The unjust steals the just's umbrella. pgp0.pgp Description: PGP signature

Any chance you are running an SMP system? You might be seeing the usage of only one CPU? Tom Veldhouse - Original Message - From: "Stijn Hoop" <[EMAIL PROTECTED]> To: "Thomas T.

I know, but I've been running top for about 15 minutes now, and it consistently shows 0.0%. I can also assume that top has gotten in sync with somehow, but then again I have more than 1 runnable process on average over the last 15 minutes, so I would suspect that some other process should also get some CPU. And of course I also ran top on other terminals -- could they all be in sync at the same time or something? --Stijn -- "Computer games don't affect kids; I mean if Pac-Man affected us as kids, we'd all be running around in darkened rooms, munching magic pills and listening to repetitive electronic music." -- Kristian Wilson, Nintendo, Inc., 1989 ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Load averages and current load are two different things. I suspect you didn't catch it when it was busy.

Hi, On a lightly loaded server top is misbehaving: it continuously shows all CPU states at 0.0% yet my load varies from 0.50 to about 3. Is there any explanation for this? Obviously, my kernel + world are in sync, running 4.8-RELEASE. Rebuilding top did no good. --Stijn ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
