ProFTPD and monit
In Amahi 7.1, ProFPTD locates its PID file (proftpd.pid) in /var/run/proftpd. The monit config file for proftpd (/etc/monit/proftpd.conf) looks in /var/run/ for the proftpd.pid file and because it cannot find it, continually restarts the proftpd service.
Changing the location of proftpd.pid in /etc/monit/proftpd.conf resolves the issue:
check process proftpd with pidfile "/var/run/proftpd/proftpd.pid"
