Hello. This is normal. When processes are shutdown they are sent signal TERM by process 0 when the service is stopped. See "man 7 signal" Sometimes the admin might want to restart after changing config files and shutting down with theTERM signal of the dovecot service happens normally with /etc/init.d/dovecot stop.
