Hanging sshd connections on remote server

This concerns the SCP and SSH tasks plugin.

After a succesfull run of a command by SSH the command completes correctly by the sshd process on the remote server never exits.

Also see Atlassian Answers: Bamboo SCP/SSH Task - Hanging sshd connections on remote agent.

As far as I can see it both in SshTask.java and in ScpTask.java a connection is build to a (remote) sshd with "ssh.connect(host, portNumber);". "ssh" being a "SSHClient" object.

This connection is never (properly) disconnected with a corresponding "ssh.disconnect".

This might cause the described behaviour.
