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
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
