I suppose these are happening because of: >>>>> dovecot: auth: Warning: auth client 0 disconnected with 1 pending >>>>> requests: EOF: 12 Time(s) Which probably happens when Postfix disconnects from Dovecot before the authentication has finished. I can reproduce these if I set up PAM authentication and then do: doveadm auth test testuser wrongpass <ctrl-c> Repeat the above a few times. Each time logs: Nov 26 13:36:13.588354 auth: Warning: auth client 0 disconnected with 1 pending requests: EOF Then stop Dovecot (or auth process at least): Nov 26 13:36:23.403778 auth: Warning: Event 0x561565277db0 leaked (parent=(nil)): auth-client-connection.c:338
