Check your firewall logs for valid incoming/outgoing packets being blocked.
I had this problem and found I'd screwed the network traffic down too tight.
This resulted in open connections building up over time. Wasn't POP3, just
normal internet traffic in my case, as I knew just vwhat packet types and
ports to allow for POP3.
