Upgraded mailscanner and perl. Now seeing these errors in /var/log/messages

The above error was captured using these two commands

tail -f /var/log/messages &

Then

tail -f /var/log/maillog

Here is the error message in /var/log/messages

root: Process did not exit cleanly, returned 255 with signal 0

Mail is still delivered fine with this error message.

If I turn spamassassin off in mailscanner.conf the error message stops.

Any ideas

FreeBSD 5.2
MailScanner-devel-4.35.5
perl-5.8.5
