All stats configuration is as default seeing by dovecot -a

   service stats {
      chroot =
      client_limit = 0
      drop_priv_before_exec = no
      executable = stats
      extra_groups =
      group =
      idle_kill = 4294967295 secs
      privileged_group =
      process_limit = 1
      process_min_avail = 0
      protocol =
      service_count = 0
      type =
      unix_listener stats-reader {
        group =
        mode = 0600
        user =
      }
      unix_listener stats-writer {
        group = $default_internal_group
        mode = 0660
        user =
      }
      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.

Do you have anything else in the logs? Did you increase client_limit for stats 
service?
