Looking at dovecot logs I discover that, each time the error shows up

Looks like I changed IMAP's disconnection reason, but forgot to change POP3's. You could apply this patch to get a better reason: http://hg.dovecot.org/dovecot-1.0/rev/e45d659a814b
But it most likely just changes the reason to "Connection closed", which means the connection got disconnected outside Dovecot (by remote client, some router in the middle or by your server's kernel due to some timeout).
dovecot: pop3[94777]: Info: user=dan@userdomain.com Disconnected:
Logged out top=0/0, retr=0/0, del=0/3, size=67947
"Logged out" means that client logged out normally using QUIT command.
