How does your watchdog script work?  Can it cope with a situation where
one spamass-milter process stays lingering around, while the actual
spam-tagging fails?  If so, I'm very interested in it.

I don't think IPv6 is related to the problem I'm coping with:
"CONFIG_IPV6 is not set" in my kernel.

The Debian supplied sendmail binary I am using has IPv6 enabled, but my
sendmail configuration doesn't use it.

Tnx anyway for sharing your thoughts.
