Mailscanner eating my resources. I just can't fix it. Help!

[Robert Borkowski]

Hello all!

I've been really trying to solve it myself, but I'm really running out of
ideas.

This is ps output? Any ideas why this happens?

If I'll terminate those continuously running processes, all is back to
normal,otherwise my incoming queue is growing and waiting to be process by
MailScanner/SpamAssassin. If everything is running normally, my CPU usage
is 5%. Otherwise, it's up to 97-99%. This happens very randomly, sometimes
all is fine for an hour and then I still one of perl processes are running
continuously and the time is growing. System load is +1 then. After a
while another process will do the same and so on.

I haven't done any changes to the configuration files. All was working and
suddenly MailScanner + SpamAssassin started to play.

Details:
Here is a message in MailScanner working directory.

Here is process 22219 which created that directory above - notice the time
10:05. (If I will do cat /var/log/mail | grep 22219 I don't see that the
process has actually started)

root@******:/var/spool/mailscanner/incoming/19673# ps | grep mails
13517  ?  S     0:00 perl -I/usr/local/mailscanner/lib
/usr/local/mailscanner/bi
19644  ?  S     0:04 perl -I/usr/local/mailscanner/lib

19673  ?  S     0:03 perl -I/usr/local/mailscanner/lib

22219  ?  R    10:05 perl -I/usr/local/mailscanner/lib

Now, I do -
root@*****:/var/spool/mailscanner/incoming/19673# kill -TERM 22219
root@*****:/var/spool/mailscanner/incoming# cat /var/log/mail | grep
i5O7lStd022171

And the message is sent.

Thanks for your help.
