Continual amavisd restarts

[Stephen Davies]

I posted this question before but didn't get any helpful responses.

My /var/log/maillog is full of messages of the form:

starting. /usr/sbin/amavisd at mustang.sdc.com.au amavisd-new-2.9.1 
(20140627), Unicode aware, LANG="en_AU.UTF-8"

followed by all of the module etc messages and ending with:

Creating db in /var/amavis/db/; BerkeleyDB 0.54, libdb 5.3

It looks as if this happens every time an email is received or sent - every 
minute or so.

Apart from filling the log, this startup sometimes takes so long that the 
sending of an email fails because there is nothing listening for the sendmail 
milter request (though a resend always works).

I am not aware of any configuration setting that makes amavisd restart but 
suspect that it might be the systemctl service.

Can anybody please throw some light on this.

Cheers and thanks,
Stephen
