Actually been over this on the list before. It's completely unrelated to that issue. It's not like some connections get through and some don't. It's completely unreproducible and *NO* POP3 connections get through at all until a reboot.
One thing to try, when you connect, see if a new pop3d process is forked. If so, strace the process (-p to connect to it), see if it's stuck waiting on some system call.
