Reverse ssh tunnel connection problem

    I am using a reverse ssh tunnel. However, sometimes the connection is broken but the server continues to think the connection is alive and well. When I try to connect to the server again I get the error:

    Warning: remote port forwarding failed for listen port 2000

    How do I recover from it? I have tried restarting the sshd service and doing killall for the sshd service. Neither worked. The only thing that has worked is to reboot the server (not a good solution).

    Is there a good way to instantly detect it and correct the problem?

    I do have the tcpkeepalive option set and it does detect it after a long time (haven't figured total time before it recovers yet.)
