Is the connection open for a long time?

Have you looked at patches? -

Hi, connections are not open for a long time.
I also restart the SSHDaemon.
i think, the exception is thrown almost the task is complete.
i send the console output again.
Finally, i did not look at patches. What patches?
Thx.

Did you application hang when you got "The host key signature is invalid" error? This error is caused by the key that is not signed by trusted authorization. My application hangs when I got this error for key exchanging. I fixed the error by updating connection state before the transport protocol stops. More details can be found the bug report I just submitted. Hope it can fix you error, too.
