I have a problem with on of my FreeBSD boxes. All of a sudden, it started acting very badly: any process takes ages to start completely, eating all CPU in the process: PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 852 root 57 0 1528K 996K RUN 0:19 91.95% 59.81% top root@ishtar ~ 1017:0 # time ps auxww ... ps auxww 0.00s user 0.01s system 0% cpu 2.197 total root@ishtar ~ 1018:0 # compare a slower box: root@lilith ~ 1005:0 # time ps auxww ps auxww 0.00s user 0.02s system 64% cpu 0.036 total root@lilith ~ 1006:0 # This strangeness lasted for about 20 minutes, persisted across a reboot (I pulled out the wrong cable...), and then just disappeared; the box works as it should. I know this is hard to asnwer, but what could have caused the effect, and what should I be looking for if it happens again? There's nothing especially interesting in /var/log/messages. BTW, top showed swap wasn't used at all. -- If you cc me or remove the list(s) completely I'll most likely ignore your message. see http://www.eyrie.org./~eagle/faqs/questions.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
