After doing so now Idle sessions crash and are unable to resume.  The `nxagent` process for the user begins eating up 100% CPU.  When I log in I get a pulse audio error.  

If I suspend the session (close the client without logging out) then reopen it right away (with just a few minutes) I am able to successfully resume the session.  However, if I leave the connection active but idle for sometimes 15 minutes sometimes a few hours, the connection terminates.  The client displays an error about the connection being terminated.  When I try to log back in.  The client pops up an error about the remote proxy and won't let me connect.

To reconnect I have to log in with putty and manually terminate the session using:

$ x2goterminatesession <session_id>
