Munin & Monit
I have setup Munin & Monit on my Debian system according Falko's How to and i have a question about this.
Before i did this it was never necessary to restart Postfix.
Since i have installed Munin & Monit, every night at 0:00 hour Monit restarts Postfix, so a new PID-file is created.
What is the reason for this?
