Hi! I've noticed a strange behavior on a server I maintain and after 2 days trying to figure it out by monitoring the server and searching the web I still cannot determine the cause of the problem.
I'm running cPanel with Exim+Spamassassin. In the last few days, during some specific periods we noticed that the server load was unusually high (>7). After a few hours monitoring it we noticed that every time the load went up, there was a "spamd" processed owned by a specific user that never finished. Once we killed it the load returned to normal values. For the past 2 days we were able to confirm this: whenever the server had a high load, there was a spam assassin process owned by that specific user hanging around and with a lot of cpu % time. Once we kill it, the server load drops dramatically. We have almost 100 accounts at that server so it must not be a coincidence that it is always that user that owns the offending process. The only clue we have is that the user had SpamAssassin disabled for a while, but enabled it again last week. He has sufficient disk quota and is not receiving an abnormal amount of emails. We tried disabling spam assassin and re-enabling it later. Any clues as to where I should next? any test I can perform? -- View this message in context: http://www.nabble.com/Strange-behavior---load-high-when-scanning-mail-from-one-specific-user-tp19898283p19898283.html Sent from the SpamAssassin - Users mailing list archive at Nabble.com.
