Disconnected: Shutting down (disconnected while authenticating) :: after mysql restart :: bug?

17 Mar 2022


      Good morning list,
i looking for a while for a solution above problem.
We use dovecot 2.3.7.2 (3c910f64b) (Ubuntu 20.04) and 2.3.13 (89f716dc2)
(Ubuntu 18.04) .
Often we have the problem, that the authentication (dovecot <-> mysql) dont
work after an mysql restart. Unfortunately i cant reproduce this problem, if
i restart the mysql-server the authentication work when the database is up
again.
If we have this problem it is enough to reload the dovecot. So that the
auth-worker will reconnect and everything is fine again.
I have tried to encircle the problem with verbose auth-logging  a wile ago
 but i only see timeouts from the auth-worker while mysql is running
But this is not the solution für the problem. Is there an option i can set
to force the auth-worker to reconnect? Maybe an timeout or something else?
Or is there an value set to high in my conf? Somethin like the idle_kill
from anvil service?
Or is it simply a bug?
