Check your running processes when you notice these delays and see which are trying to hog your CPU time. Handling inordinately large messages resulting in a lot of disk i/o is one of the possible causes. Check your logs to see what other email is being processed when the delays occur, it could just as easily be someone sending bulk email through your server. Or it could be high time for a hardware upgrade. :) > > > and your QueueLA in /etc/sendmail.cf ? > > We do not have this explicitly set. > What would be a good number considering our load > average? > I think 5 is quite reasonable. I'd see to it that I reduced the load before letting it engage in a vicious circle of processing even more mail and increasing the load above what it already is. It's a matter of what you think is practical. hth -ac -- ============================================================== Alex Charalabidis (AC8139) 5050 Poplar Ave, Ste 170 Systems Administrator Memphis, TN 38157 WebNet Memphis (901) 432 6000 Author, The Book of IRC http://www.bookofirc.com/ ============================================================== To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
