I would guess that maybe xmms (or some other threaded app) is your hidden CPU consumer. The kernel does not calculate %CPU correctly for libkse-threaded programs, and they usually show up as 0% all the time. The TIME column does update correctly, though. If you switch to libthr with libmap.conf, you'll get accurate threaded %CPU reporting. -- Dan Nelson [EMAIL PROTECTED] _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
