While debugging with we encountered an issue where call to `fuser 8670/tcp` it got blocked for minutes
- in fact we did not ever see the agent start and had to comment the call. Two
- Need timeout for such calls (lets also research and see why the call may get stuck). We checked that the port was free.
- Need more debug logging in the initial start up path to help debug what command is getting stuck - in main.py, and PingPortListener.py lets see if more debug logging can be added
