For whatever reason, your session is not being terminated correctly.
Try adding the following setting to your /etc/ssh/sshd_config file
so that sshd notices that the client has gone silent:

ClientAliveInterval  120

This will test a silent client every 2 minutes.  If 3 attempts (ie. 6 minutes
of silence) doesn't yield any response from the client it will be disconnected.

HTH,
