[Dovecot] authentication process fails when starting 2nd dovecot

[Cipriano Groenendal - TransIP]

Hello,

With dovecot running already, (accidently) starting another dovecot seems to
break the authentication process of the first dovecot. Login will be
impossible untill dovecot is restarted.


# dovecot
Fatal: listen(143) failed: Address already in use

## Wait several seconds.

# telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK Dovecot ready.
0: logout
* OK Waiting for authentication process to respond..
0: logout
* OK Waiting for authentication process to respond..

Also, in the logfiles the following entries will appear:
--
Mar 26 12:11:21 virt6 dovecot: pop3-login: No authentication sockets found
Mar 26 12:11:21 virt6 dovecot: child 38054 (login) returned error 89
Mar 26 12:11:23 virt6 dovecot: imap-login: No authentication sockets found
