Hi Dan: We had a similar problem. I posted a couple of messages regarding this very issue. We were having CPU at 100% for minutes.. & in one case when a mail list hit our server with a lot of users receiving the message at the same time the CPU was at 100% for almost an hour. We could not do anything... Finally the Declude processes disappeared and all was back to normal again.
What I noticed was the cause more than anything else was the IP4r tests. Declude appears to be fast in filtering and everything that it does. The IP4r tests are a different story and naturally out of Declude hands. We had a lot of them and by taking them off it brought things to normal. I stated this in an earlier posting- we are not doing all of our IP4r tests in IMail version 8. It works much faster and since it caches it seems like it works great. We have about 60 IP4r tests (majority of what is listed in Declude/junkmail/manual.htm site. We will take some off and add others as we find their effectiveness but for now we are using a lot of them and no problem. I am interested to see if this helps you if you try it.

Suddenly the CPU load graph stopped looking like its normal Donky Kong video game simulation (up and down) and more resembled a 100% highway with a few dips. Declude processes were taking quite a while to clear before finishing, to be replaced by another. I pulled out some multi thousand line tests and it nary made a dent. Just before bringing our 3rd server into the fold, things quieted down. While I've already ordered 2 new dual processor 1U's, I want to par down (if not eliminate) the variables invovled: 1) If an external DB query slowed things down, delaying each Declude process, would Declude still show high CPU consumption while waiting and would the graph still be pegged? If not, is there any situation external to my server that would? 2) Is it possible for Declude to be consuming CPU cycles while idling for some other reason? 3) If something else is running in the background, eating cyles, does Declude 'look' like its working harder? 4) If a user (or users) all received masses of attached files (say multi megabyte), would this slow things down in the way described? 5) When a new client reports having 30 users, whats the best way to decipher if this is the case? Is there a log analyzer that inventories unique addresses (understanding that 1 user can have many addresses). Thanks!
