I'm using SSHProxyEngineSetLauncher to start an ipcluster on a remote machine which uses condor.
When stopping SSHProxyEngineSetLauncher condor_q still shows ipengines in the queue.
I think this is because SSHProxyEngineSetLauncher kills the ssh connection which runs ipcluster.
With this approach the ipcluster is not able to correctly shut down and kill the engines.
Maybe it is possible the send a shutdown signal before killing the connection
