You may be logged in on another machine. Close all connections on all machines and wait 10 minutes to check again. Some mailservers will not recognize an improper disconnection in some instances. Your account may be "Poplocked". You can either wait for the "poplock" to time out, or have someone shell into the mailserver and kill the mail task running on your account. If you are not logged in on another machine or poplocked, then someone may be using/downloading from your account, or something is wrong with your account.

This is a possible corruption of the pop3uidl file. Close your internet connection and all programs. Search for the file pop3uidl and delete it. Reconnect and it should work. Repeat step 1 with a reboot before you check your mail again. You may have a corrupt or a very large file attachment on the mailserver. Large file attachments, mail that are missing headers, or mail that do not conform to the mail RFC's can cause this.
