Before I had an K6-2/450 and few problems (at least not the following). Now I see the system going nuts with zillions of messages "microuptime went backwards" in the syslog. Actually the system becomes unusable because it is so busy writing these messages. At the same time the clock moves rapidly forward. Within a few minutes the output of the date command advances by several hours. I'm not sure when this happens but it seems to be start when the system is under load of a big compile job. I.e. I can use it for hours with editing tasks but when I start to compile stuff -- not the first time but after a while -- the problem begins. I also observed the problem when using gzip on a very large file. More info: FreeBSD europa 4.0-STABLE FreeBSD 4.0-STABLE #7: Wed May 31 13:11:13 CEST 2000 root@europa:/usr/src/sys/compile/EUROPA i386 I cvsup-ed and made world (and kernel) a few days ago. I have 256 MB RAM but otherwise no fancy stuff (one IDE drive, an old RIVA-128 graphics card). I don't think it is a thermal problem because I have a good cooler and the BIOS reports temperatures under 40 degree Celsius. Also I reduced the system clock to see if that helps. It didn't. I would be grateful for any hint, as I'd neither like to downgrade my hardware nor my operating system. -- Dirk Zoller Fon: 06106-876566 Obere Marktstraße 5 e-mail: duz@sol-3.de 63110 Rodgau To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
