Hi again, After i run the command "node chat.js &" and try to end it whit CTRL + C. I still get debug information. when i then tries to run the command "node chat.js &" again then I get "warn - error raised: Error: listen EADDRINUSE". That means that the port node chat.js tries to lissen to (8080) is already in use because CTRL + C did't terminate the other running process of chat.js. What can I do to close chat.js?
