You probably had lots and lots of pop3 processes running, overflowing
the number of available fds for logging. v1.1 gives a warning about this
at startup.

Change your ulimit or settings so that "ulimit -n" before starting
Dovecot gives a somewhat larger number than max_mail_processes +
login_max_processes_count.
