Error: conn unix:/run/dovecot/stats-writer : Timeout waiting for handshake response
Hi, I'm using ubuntu 22.04 and installed dovecot 2.3.16.
I did some initial testing with 100 email accounts and everything seemed to work perfectly the same as dovecot version 2.3.16 on another server. So I performed the migration of approximately 30 thousand email accounts, but the following error started to appear and I know well what to do:

Does anyone know anything about this problem that can help me?
Do you have anything else in the logs? Did you increase client_limit for stats service?

soon after starting dovecot these errors start to appear. I will send the first errors after doing a service dovecot start

All stats configuration is as default seeing by dovecot -a

user = $default_internal_user
vsz_limit = 18446744073709551615 B
}I don't use this dovecot stats service and I don't have metrics configured. Actually I wanted to know if it is possible to deactivate it because we do not use it here in the company.
