No. It means that it disconnected a client that wasn't yet logged in
because login_max_connections was reached. It should happen only if
login_max_processes_count was reached. Perhaps there's still a bug
somewhere in there.. How many imap-login processes do you have running?
Increasing login_processes_count probably helps for now.

With these settings it should have allowed 32*128 connections / ssl
proxies until the connection queue full error would have happened.
