This usually happens when you have a background process connected to
the tty used by your SSH session.
This usually happens when you restart a daemon ("service xxx restart"
or "/etc/init.d/xxx restart") and the script or the program does not
detach itself from the tty, which it should do if it is a proper
daemon.
You can use "ps -f" (before you close the session) to see which
processes are attached to your tty, after that, if you log out the
session and it hangs, you can look into those programs that were
running on your tty and see if they are causing that.

If you want to force disconnection of the SSH session without having
to close the terminal or window, you can type <Return> then ~. (tilde
followed by dot), this will terminate the SSH client process.
HTH,
Filipe
