I have installed PM2 to keep my node application running. ()

It works great, however...

Since installing and running my app with it

pm2 start app.js pm2 stop app

I am no longer able to run my app using

node app.js

Instead I get the following error:

domain.js:66
    throw er;
          ^
Error: listen EADDRINUSE
    at errnoException (net.js:770:11)
    at Server._listen2 (net.js:910:14)
    at listen (net.js:932:10)
    at Server.listen (net.js:998:5)
    at Function.app.listen (/home/ssp/node_modules/express/lib/application.js:535:24)
    at Object.<anonymous> (/home/ssp/app.dev.js:22:5)
    at Module._pile (module.js:449:26)
    at Object.Module._extensions..js (module.js:467:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)

This error usually happens when you try to run the same thing twice.

However app.js is not running. I have stopped it in PM2. And when I type

ps aux | grep node

To check if it is still there, it is not.

Uninstalling PM2 does not seem to fix this. Any ideas what is going on?

• What does pm2 list say? is it still keeping the port open "for convenience"? – Mike 'Pomax' Kamermans Commented Sep 20, 2013 at 0:27
• Since pm2 overwrites the process title, your app won't show up using the ps mand you mention; either grep for app (instead of node) or use pm2 list instead, as Mike suggests. – robertklep Commented Sep 20, 2013 at 6:53

Overall this means that you have a process running on the same port, you can kill it using:

sudo kill $(sudo lsof -t -i:8080)

just replace 8080 with your server port

If you get this problem do a :

pm2 kill

(it kills pm2 and the port is freed)

This bug is really strange and impact only v0.10.x node versions.

I remend you to use the node v0.11.10
