Heroku Erreur H12 (Request timeout) question

Je sais que c'est un autre Heroku Erreur H12 (Request timeout) question. Il semble que le problème est causé par plusieurs raisons. J'ai déployé un Rails 3.2.2 application sur heroku il ya quelques jours. Lorsque j'essaie d'accéder à mon application via le navigateur. J'ai eu

Application Error
An error occurred in the application and your page could not be served. Please try      again in a few moments.

If you are the application owner, check your logs for details.

Je pars donc à la recherche sur Internet comme d'habitude à comprendre ce qui ne va pas. Puis-je apprendre à utiliser heroku journaux pour vérifier mon fichier journal. Voici le fichier de log.

Après examen des logs, je ne comprends pas vraiment quel est le problème. J'ai fait la recherche sur Internet. Il semble qu'il y a de nombreuses raisons qui peuvent provoquer ce problème. Je sais qu'il ya peut-être quelques bugs dans mon application. Mais je ne peux pas dire quelle partie de mon code est faux.

Et , je peux utiliser mon appli dans mon ordinateur local. Donc, savez-vous quel est le problème ou comment repérer le problème?

Mise à jour:

Quand je fais
git push heroku
