I notice in the logs, that the number of imap-login Login: lines matches the number of Disconnect: lines in the log. For pop3-login, there are 111 Login: lines and only 8 Disconnect: lines.
Nevermind. A closer look at the logs shows this is a complete red herring, the logs are unrelated.
Still digging.

We are running dovecot 1.0.5 on a test server, with FreeBSD 6.2 (though I have noticed the same problem since dovecot versions in the 0.99 range).
We don't have very many simultaneous pop/imap users, but we have a proliferation of pop3-login processes.
Currently we have 128 such processes. We have 11 imap-login processes, but only a few actual imap processes running.
Is this normal? Can we stop it?
Do you have lots of login attempts? If you have more than 64 concurrent POP3 login attempts, you'll get 128 pop3-login processes. http://wiki.dovecot.org/LoginProcess explains more.
