spamass-milter stops working

[Straub Herbert]

Hallo,

the spamass-milter works very fine, but sometimes it stops working. I use it with the following sendmail.mc settings:

INPUT_MAIL_FILTER(`spamassassin',`S=unix:/var/run/sendmail/spamass.sock,F=T,T=C:3m;S:1m;R:1m;E:3m')dnl

If the error occours, then the ps axlw shows the following:
...
 040     0  2901     1   9   0 274940 1592 rt_sig S   ?          0:00 [spamass-milter]
...

The /var/log/mail/mail.log shows:

After restarting the spamass-milter (/etc/init.d/spamass-milter restart), ps axlw shows:

 /var/run/sendmail/spamass.sock -r 6
    040     0 27446 27444   9   0  5968  888 poll   S    ?          0:00 /usr/sbin/spamass-milter -p /var/run/sendmail/spamass.sock -r 6

I use spamass-milter 0.2.0. Any hints?
