Interesting! It seems like the server is trying to handle a request for 
a channel that has for some reason been closed.
If i modify the patch like this ...

diff --git a/lib/ssh/src/ssh_connection.erl b/lib/ssh/src/ssh_connection.erl

#connection{channel_cache = Cache} = Connection,
           ConnectionPid, _) ->
     if WantReply == true ->

+                   undefined -> %% Chanel has been closed
+                       {noreply, Connection}
+               end;
        true ->
            {noreply, Connection}
     end;

... you should not get the below crash. But I am wondering if your 
application will
now behave as you expect?  Can you give me any more information on the 
senario
of your application. It would like to be able to write a minimal test 
case that provokes
the problem.
