[Mailman-Users] mailman load is overkill!

[benoit joseph]

Hello all,

I'm new to mailman, i've been running majordomo for now two years but i 
switch because the mailman web interface is just great! ;-)

Here is my config:

my mail server:
   SMTP sendmail with access_db enabled and DNSBL check disabled for 
localhost on gentoo linux
   IAMP cyrus-imapd

python version: 2.2.3 (gentoo version: 2.2.3-r5)
mailman version 2.1.2 (gentoo version 2.1.2-r1)
mailman delivery: SMTPDirect

about 20 mailing lists in 4 virtual mail domains.
about 500 users across all mailing lists

My problem is that mailman qrunner (the Incomming one) is taking 100% 
even for few messages...

I checked in the error log and I find this error (those errors are very 
-very- long):

I don't know what to do...

Any suggestion is welcomed...

Thanks for advance,
