I think my issue was also with autowhitelist. I hate the tool. I had a
MySQL database table for autowhitelist that was 2GB with an index just as
long. That filter never worked to my expectation and I finally killed it
which seemed to help prevent spamassassin not cause timeouts.

Also, be sure that you do have "bayes_auto_expire 0". Auto_expire happens
while an smtp session is active, and the sending server may time out if
the process takes more than a couple minutes, which can happen pretty
easily depending on your processor and how busy it is.
You can run a daily cron job to handle the bayes database expirations:
#!/bin/sh
# written 11/17/06 by Eric Shubert <e...@shubes.net>
# force journal sync and expiration of spamassassin bayes database
#
sa-learn -u vpopmail --force-expire
chown vpopmail:vchkpw /home/vpopmail/.spamassassin/bayes_toks

I also ran into a similar problem a while back, but in my case, I would
see multiple copies of the same email because the time out would occur
after the whole message had been transmitted, but before rcpt
acknoledgement had occurred. No messages were filtered down to me
regarding mail delivery failure, but I would assume that was happening as
well like you describe.
What Jake says should fix this problem of "prefork: server
reached --max-children setting, consider raising it". I did this and
also upgraded spamassassin and clamd, both which were out of date on my
system.
After making the change...
run the following 2 commands to commit the changes without having to
reset the whole system ...
svc -d /var/qmail/supervise/spamd/
svc -u /var/qmail/supervise/spamd/

I use Qmailtoaster (stock iso image install) as a front end spam/virus
scan for our Exchange system and recently we have started recieving a
large amount of non delivery errors to people outside of our domain
trying to send mail to us. Our mail volume is high.
The errors are all basicaly the same (examples below from forwards of
failed messages)
conversation with nxu02.ptr-online.COM[65.99.245.52] timed out while
receiving the initial server greeting

As I looked at some of the logs, I noticed the following happening alot:
from spamd logs:
@4000000049cb87e92a31cfac [2374] info: prefork: child states: BBBBB
@4000000049cb87e92a31d77c [2374] info: prefork: server
reached --max-children setting, consider raising it
I have no clue where to raise the child limits.
when I run top, the system has 1.2gig ram free all the time so I do not
think it is a memory issue.
Does anyone have any ideas? This is driving me nuts.
