We currently use the following configuration for blocking Spam: Solaris 8 Mimedefang 2.41 SpamAssassin 2.63 Perl 5.8 Sendmail 8.12.11
Over the weekend, I noticed several message in the syslog that the milter timed out, and that some messages were taking several hours to finally get through the system. We were still blocking spam, but it was taking a long time. I was getting reports from users that they were not getting messages from clients, and would see in the log that their message was refused because the milter was too busy to accept it. This never used to happen, we would get emails right away even after they went through SA. I have tried adding more mimedefang instances to the multiplexor, but they just get used and get busy. I have 20 running right now, and all are busy. Does anyone have any idea why this just started happening? I thought maybe it was because of some of the new rules that I installed, but even after turning most of them off, I still have the problem! I have the following rules installed (all downloaded recently): 99_FVGT_Tripwire.cf airmax.cf random.current.cf antidrug.cf backhair.cf sa-blacklist.cf bigevil.cf sa-blacklist.current.uri.cf bogus-virus-warnings.cf chickenpox.cf evilnumbers.cf weeds.cf I ran a spamassassin -d --lint and receive no errors. Here are some of the errors in my syslog: Mar 24 09:33:42 spawn mimedefang-multiplexor: [ID 316382 mail.info] Killing busy slave 17 (pid 23428): Busy timeout Mar 24 09:33:42 spawn mimedefang[5240]: [ID 847421 mail.error] Error from multiplexor: ERR Filter timed out - system may be overloaded (consider increasing busy timeout)Mar 24 09:33:44 spawn mimedefang-multiplexor: [ID 364399 mail.info] Slave status: Stopped=0 Idle=0 Busy=20 Killed=0 Queued=0 Msgs=3193 Activations=3183Mar 24 09:33:44 spawn sm-mta[23419]: [ID 801593 mail.error] i2OGSDCS023419: Milter (mimedefang): timeout before data read Mar 24 09:33:45 spawn sm-mta[23419]: [ID 801593 mail.info] i2OGSDCS023419: Milter (mimedefang): to error state Mar 24 09:32:10 spawn sm-mta[23532]: [ID 801593 mail.info] i2OGW3iQ023532: Milter: data, reject=451 4.7.1 Please try again later Any help would be greatly appreciated. - Matt
