Hi all!

I would like to ask for your help about an sa problem.
Somethimes (random or when a lots of mails arrive) some spamd children
gets stucked in, what pushes up the load (~40), and enormously eats memory
(~6-7Gb). It started about 1-2 weeks ago. This makes the complete mail
server unuseable, especially the exim4 smtp (gives timeout), the dovecot
works fine, but slowly. It goes until i have to do a killall -9 spamd,
/etc/init.d/spamassassin start.
I use spamassassin 3.2.1 (comes with ubuntu server lts) and
exim4.
