Nodemon keep crashing with "already in use error"

I am using nodemon with express.js on localserver with 8080 port.

nodemon keeps always crushing after any change I do in my files with this error:

events.js:292
      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRINUSE: address already in use :::8080

  code: 'EADDRINUSE',
  errno: -98,

  address: '::',
  port: 8080
}
[nodemon] app crashed - waiting for file changes before starting...

I can fix it just by adding space or enter, but nodemon will crush again after another change I will make.

My app.js listener:

app.listen(process.env.PORT || 8080, process.env.ip, function(){
    console.log('Server is running!');
});

If you running on linux you need to kill all process at 8080 (or any port you get stuck)

kill $(lsof -t -i:8080)

Then run your application again. I think you make some bug in your code so it's affect to you nodemon.
