Process did not exit cleanly

[Jon Miller]

Debian 3.1
Mailscanner 4.41.3-2
Spamassassin  3.0.3-2
Postfix  2.1.5-9 
MailWatch 1.0.3

I've had to rebuild Mailscanner and Spamassassin over the last few days and did a complete uninstall and reinstall.
Mail started working okay both incoming and outgoing, had a look at my /var/log/messages and started noticing a continuing entry of the following messages.  Anyone know the fix?

I getting repeated messages in /var/log/messages stating:
