Limit the size of spamd

[Network Operations <no...@theabysss.com>]

List;

We are an isp that currently runs through either qmail-scanner or 
Plesk spamassassin. 2.6x and i believe 3.x. We are having issues with 
spamd getting into the 125+mb process size at 4 to 5 processes. We 
are running from Fedora to FreeBSD 4.9+ and qmail is the MTA. I have 
looked and have not been able to find a way to limit scanning to to 
messages <1mb. Any help would be greatly appreciated.

1MB?? wow thats a lot.. we use SA and exim and dont scan any mail 
greater than 80k. Its a simple exim acl statement...

warn    message       = X-Spam-Score: $spam_bar ($spam_score)\n\
                           X-Spam-Score-Int: $spam_score_int
           condition     = ${if <{$message_size}{80k}{1}{0}}
           spam          = nobody:true

our process stay between 30-40Meg and means we can run 10 children at a 
time.

Are you running any add-on rulesets? In particular, are you using bigevil.cf?

Investigate the --max-conn-per-child and --max-children command line flags 
for spamd. While not directly addressing the issue of SA processes expanding 
to consume all available memory, --max-conn-per-child will at least kill and 
restart a child after x number of messages, which definitely does the trick 
for me. I have --max-conn-per-child set to 10, and --max-children set to 5. 
SA only processes about 600 messages per day, but with a full complement of 
SARE rules, it keeps the SA processes down to a trim 40-60MB per process.
