Cutting a lot of debug statements here - see

for my complete original messages

I finally found the problem - the spamassassin bayes db. For some
reason Perl (or really spamassassin) exited on signal 11 when reading
the bayes db. The reason it took my so long to find the problem was:

1) I was lazy and in stead of testing with
      su vscan -c 'spamassassin -D -t < msg.txt'
   as recommended, I just ran
      spamassassin -D -t < msg.txt
   as root. The later command didn't exit with signal 11, while the
   first did - it stopped after

bayes: found bayes db version 3
    
2) The debug in /var/log/maillog (as posted in my earlier messages) was

[...]

bayes: tie-ing to DB file R/W /var/amavis/.spamassassin/bayes_seen
bayes: found bayes db version 3
locker: refresh_lock: refresh /var/amavis/.spamassassin/bayes.lock

It didn't stop at the same point - "bayes: found bayes db version 3".

3) sa-learn didn't report any problems with the bayes db.

Anyway, the solution was simple - "rm -rf /var/amavis/.spamassassin/*".

I guess I should have asked on the amavisd mailing list, but at least 
this is documented here now for other FreeBSD users that get this problem 
after upgrading from Perl 5.8 to 5.10.
