Note that you have 1 running and 37 sleeping processes in your "top" output. That would give you a load average of 1.0 over time. If, in addition, cron-driven processes woke up, or you ran something for a little bit, or some other process(es) woke up for a short time, that would account handily for the first two numbers in the load average vector. I account for the third by postulating that you had zero processes running for a while. -- Mike Andrews mikea@mikea.ath.cx Tired old sysadmin since 1964 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
