-------------------------------------------------------------
  The error is due to a port conflict on 62001, where this port has been occupied and this prevents the new python engine session from starting.

"Error starting server socket 62001 for contained engine
java.net.BindException: Address already in use: NET_Bind"

Please follow below mentioned steps to resolve the issue:
--------------------------------------
On Node manager machine where you have configured Python service, please check if you can find any stray Python Java process via ProcessExplorer (Open Task manager to verify)

Or if you can find any process running on port 62001 (for example, using command "netstat -ano | findstr 62001" in a command prompt window).

If yes, please kill any process that has been started on port 62001 (e.g. command "taskkill /PID <PID> /F"). 

Then restart the Python service from Nodes & Services in Spotfire server UI.
