I saw this on 7.0-7.2. One of 7.2-S is, for example, from 2009.10.04.23.59.59. I believe I saw the same CPU usage on FreeBSD-6 too. -- Igor Sysoev http://sysoev.ru/en/ _______________________________________________ freebsd-stable@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscribe@..." |
