What it means is that you have this enabled and user tries to log in with POP3 while another POP3 session already exists and isn't dying after 5 minutes. Some possible reasons: - User using multiple POP3 clients? - User using dialup and connection dies while downloading messages? - User has huge mailboxes that take a long time to download? In any case setting pop3_lock_session=no gets rid of these errors, although that then violates POP3 RFC.
