Heroku Boot Timeout (Error R10)

Every time I launch my app it cannot get past the 60 second point without:

2012-05-06T22:41:11+00:00 heroku[web.1]: Stopping process with SIGKILL
2012-05-06T22:41:11+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
2012-05-06T22:41:11+00:00 heroku[web.1]: Process exited with status 137
2012-05-06T22:41:12+00:00 heroku[web.1]: State changed from starting to crashed

Here is my Procfile:

web: bundle exec thin start -p $PORT

Any responses will be thoroughly appreciated.

Solution

  • If your app does take longer than 60 seconds for "good" reasons, you can work around the 60s boot time limit with https://github.com/dblock/heroku-forward.
