SO I have two quick questions: 1. Is there any way to know which processes are blocked (which processes are those 7 processes) ? 2. Why doesn't this number ever go back down ? I know for a fact that there are times that server utilization goes way down and barely anything happens on the server, but even after "resting" I still see between 6-9 processes in the blocked column. At some point they have to become unblocked, right ? Or is it possible for some process(es) to be stuck in a blocked state ? thanks! _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
