I created a sample app called stock portfolio manager
https://github.com/rohanmoitra/foliomanageを作成し、heroku にデプロイしました。しかし、heroku rake db:migrate を実行しようとすると、タイムアウトになり、次のエラーが発生します。
2012-10-22T22:28:35+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process
failed to bind to $PORT within 60 seconds of launch
2012-10-22T22:28:35+00:00 heroku[web.1]: Stopping process with SIGKILL
2012-10-22T22:28:36+00:00 heroku[web.1]: Process exited with status 137
2012-10-22T22:28:36+00:00 heroku[web.1]: State changed from starting to crashed
Has anyone encountered this error before? Any help would be deeply appreciated
