[Dovecot] Dovecot rc23 and rc24 freeze after authentication

I had our production systems running on rc23, however we ran into
problems when the server was under heavy load. Eventually, the
server would begin to freeze all imap connection after authentication
(according to the logs). A user would connect, authentication would
succeed, and then the connection would sit until timing out. No
error logs were produced. Upgrading to rc24 did not resolve the
issue, but reverting to rc22 has.
