Well, you could do something like:

service auth-worker {
  executable = auth -w -L -o info_log_path=/dev/null
}

Or you could increase process_min_avail so processes wouldn't all the time be created/destroyed and you wouldn't have so many mysql connection messages.

But then again, I can't really think of any use for those messages. LDAP for example doesn't log about it. So removed from v2.2 unless someone gives a good reason for why they should stay: http://hg.dovecot.org/dovecot-2.2/rev/33e78edac8f5
