Such connections do not exist on the front-end that connects to director hosts, so it's something between director and dovecot only.

from either director process, and ESTABILISHED. A deeper analysis shows me that there ltos of connections from the same
users to BOTH dovecot instances, but as I am using director, this shouldn't
happen, right? Ok. The thing is, one of the dovecot instances have only old
connections (like 3 days old) and the other dovecot have some old and some
newer connections. So, director is redirecting recent connections to the right dovecot, as
expected, but it is keeping many of old and unused connections open,
consuming resources. output of doveconf -n from dovecot:
