Upon rebooting our Dovecot server, I got these:

However, everything does work okay. I believe we ran into this once before and reported it and I had thought Timo fixed it. It seems that imap-login and pop3-login attempt to connect to the auth server before it is fully operational. I don't recall what the fix was supposed to change, but it doesn't seem to have fully fixed it. .. login_processes_count: 32
I think the problem is simply that all the 32 imap-login and 32 pop3-login processes are created at once and they all connect to dovecot-auth at the same time.
Hmm. Actually there exists code to retry the connecting for one second, but I'm only checking against EAGAIN (which pretty much never happens). It should check also for ECONNREFUSED: http://dovecot.org/list/dovecot-cvs/2007-March/008214.html
