Error: listen EADDRINUSE :::15454

[noahcoetsee]

This is an error. Any idea what caused it when I ran the server.js using Cloud9.... I'm not sure what is going on!

Error: listen EADDRINUSE :::15454 at Object.exports._errnoException (util.js:907:11) at exports._exceptionWithHostPort (util.js:930:20) at Agent.Server._listen2 (net.js:1250:14) at listen (net.js:1286:10) at Agent.Server.listen (net.js:1382:5) at Object.start (_debug_agent.js:21:9) at startup (node.js:70:44) at node.js:974:3

Sounds like you tried listening to a port which is already in use... Maybe it's used by a different instance of IOGrid. You can try running this in the console (warning, it will shut down all your Node.js processes):

killall node

Then try launching again.
