SpamAssassin have many fails on my ubuntu 12.04

[Damien Guillaume <da...@abstergo.fr>]

Hi All,

I post on this list because since several days I've problems with my SpamAssassin. 
He crash several times in 1 day. I need just to make /etc/init.d/spamassassin start and it work again.

In Debug, I've that on the last 10 lines before the crash:

That's my /etc/default/spamassassin:
ENABLED=1
SAHOME="/var/log/spamassassin/"
OPTIONS="-D -u vmail --sql-config --nouser-config --daemonize --max-children=15 --create-prefs --setuid-with-sql --helper-home-dir=${SAHOME} --syslog=${SAHOME}spamd.log"
PIDFILE="/var/run/spamd.pid"
CRON=0

I've try to reduce the max-children of 10 or 5 but the Spamassasin crash same if I've 15 or more ...

Have any people in the same situation ? Or have you a idea what's I can check ?
SpamAssassin version 3.3.2
  running on Perl version 5.14.2

That's is my "transport" with postfix:
spamassassin    unix            -               n               n               -               -               pipe
                flags=Rq user=vmail argv=/usr/bin/spamc -u ${user}@${nexthop} -e /usr/sbin/sendmail -oi -f ${sender} ${recipient}
