DirectAdmin sent a warning message stating:
The service 'dovecot' on server insert.server.here is currently down
Using DirectAdmin’s Service Monitor to restart it resulted in this error:
/sbin/service dovecot restart 2>&1
So I SSH in and try to restart it manually from the command line:
/sbin/service dovecot start
I receive this error:
Fatal: listen(0.0.0.0, 993) failed: Address already in use
So we need to find you what is hogging port 993 by using the lsof command:
lsof -i:993
lsof tells me that PID 2083 is bound to port 993 so I kill it:
kill 2083
Dovecot starts successfully. Yay!
