Heroku - crash all the time

Question

I am developing node.js app on heroku. For now it runs on single (free) dyno.

For some reason suddenly my app crashed and now it crashes all the time (I observed it after adding NewRelic and Librato addons - app is kind of restarted when adding those addons) - app crashed for the first time after one of those addons were added. So I removed both addons but problem still remained. I wanted to check whats wrong and I commented my app code and replaced it with simple example from the web:

index.js

var http = require('http');
http.createServer(function (req, res) {
   res.writeHead(200, {'Content-Type': 'text/plain'});
   res.end('Hello World\n');
}).listen(process.env.PORT);
console.log('Server running at http://127.0.0.1:1337/');

Procfile

web: node index.js

engines in packages.json (node installed by heroku is 0.10.26)

"engines": {
   "node": "0.10.x"
},

This code works on my pc (tested with foreman). When I try to deploy it to heroku app crashes - here is the log:

2014-04-25T09:43:42+00:00 heroku[slug-compiler]: Slug compilation started

2014-04-25T09:43:57.945393+00:00 heroku[web.1]: State changed from starting to crashed

when I try to heroku restart:

2014-04-25T09:44:54.235545+00:00 heroku[web.1]: Process exited with status 8

This make me crazy - I deployed many node apps to heroku which are runing in production and had never such problems - whats going on???

When I changed node engine version to 0.10.20 (I am using this v localy) then app started and was working but when I did heroku restart it crashed again...

State changed from up to starting

after second restart app was up and runing again, and after third restart it crashed again (it always crashes/exits with status 8).

Answer 1

The problem could be on Heroku itself. There was an incident report created about an hour ago but it is still unclear what is causing the problem: https://status.heroku.com/incidents/614

Meanwhile, you might want to rollback to the previous working build of your app via HerokuDashboard.

Answer 2

add this config to package.json:

 "scripts": {
"start": "node index.js"},

index.js is name of of file you want to start you app from here like www.js or server.js
