Dovecot auto restart (watchdog)

Due to backup unfortunately the server was briefly left without space and at that point dovecot service stop in the night around 00:57 min.

The server had free space soon after the backup, and in the morning at 08:00am when I checked, there was currently 20GB of free space on the server, but of all the services only the dovecot was not running.

Does the centos webpanel have some watchdog that monitors services that don't work so that it can autostart them, and how come the dovecot isn't started?

Tnx.
