I'm posting this to give as much information as possible, not to put the guys at declude in a bad light. They're doing a great job and we love their product!
Something either wrong with all 4 of our servers or there's a big problem in 3.x I've got 4 Dell PE 1650's dual proc. 1.4Ghz machines with 2GB ram each, Windows 2003 Server Std, SP1. We run Sophos AV for the OS itself and exclude the entire \imail folder (and its sub-folders) All 4 are behind two clustered Foundry Server Iron load balancers. The load balancer does a round-robin redirect of SMTP traffic (A,B,C,D,A,B,C,D). We do about 400,000 messages a day which means about 100,000 per server in Imail Gateway mode only. The only services we run on Imail are Monitor, SMTP, and QueueMgr. one AV scanner (fProt -- on demand not installed). Message sniffer Spamchk Various filters We've been running declude for 3-4 years with no problems. In 2.06 we ran MAXPROCESSES at 30 and could process about 1000 messages in the spool folder in less than 4 mins. About a month ago we went to 3.x and suffered from lots of decludeproc crashes. Started at maxthreads at 30 -- CPU ran constantly at 100%. We finally had to drop to maxthreads 15 to get a good "spike" pattern. Working with declude (which by the way are always helpful) we tried to isolate the problem. Removed the AV scanner, removed all externals, etc. Decludeproc still crashed. We thought it was specific messages but after testing we would move the messages in the \review folder back to the \proc folder and decludeproc would NOT crash. Anyway, we had to go back to 2.6.11 the other day. Too many crashes and delays in mail delivery. When decludeproc would crash, Imail SMTP would continue to deliver, the proc folder would build up causing a massive queue backup. Too many users complained so we reverted. The servers are back to normal FAST delivery. I should also point out that when 3.0 would run (between the crashes) it didn't keep up with the load that 2.6 could. In other words, if we would put 1000 messages in the \spool folder in 2.6 we could process them in about 3 mins. In 3.0 1000 messages in the \proc folder would take more like 8 mins to clear out. --- This E-mail came from the Declude.JunkMail mailing list.
