The good news was that 3.01 was really, really good at tagging spam and I'd love to get back to it. The bad news was that no matter what I did I could not stop the memory problems and the resulting lock-ups with 3.0 AND 3.01. I've been reading and searching this group from the moment that I upgraded my mail server to 3.01 (about 10 days ago) and believe I've tried implementing every solution that has been offered for people that have posted about memory and load average problems. Maybe I've missed something, maybe I'm not getting it, maybe someone can help.
My set up is this: A dual processor RedHat 8 machine running Qmail/Spammassassin/Clamscan via qmail-scanner 1.24 with 1GB of RAM. I've got about 500 email accounts and run spamassassin in fast mode. I use a straight forward system-wide bayes setup with no individual user bayes preference files. I don't use BigEvil that I know of unless it comes built in to 3.+ and is on by default.
When I run spamassassin 2.64 I generally have about 450MB of free memory and again, everything runs fine. $LANG is set to en_US for PERL 5.8.
When I run spamassassin 3.01 my machine starts with about 400MB of free memory but that gradually evaporates over a period of anywhere between 1 and 24 hours. Eventually I start getting into swap and qmail-scanner starts complaining about not being about to talk to spamd, a ton of perl processes start running and multiplying, the spamd daemons appear take up a bit more memory (though not a lot more, 31MB vs 24MB) than when they started, and rather quickly my 1 minute load average goes up to somewhere over 20.00 from a normal of about 0.36. At this point my mail server obviously stops responding and I've got to kill spamd and all of its perl processes before my customers come in the door and kick my ass.
I've disabled auto-whitelist'ing, wiped out my bayes databases, used the -m switch to change the number of spamd's that are allowed to run (I've tried as few as 3 and as many as 25) and nothing has worked.
Can anyone see anything that might get me back on track? I *want* 3.01 to work bad...
Thanks so much.
