Ошибка Heroku H12 (тайм-аут запроса)

Я знаю ее другой Heroku ошибка H12 (тайм-аут запроса) проблема. Похоже, что проблема вызвана многими другими причинами. Несколько дней назад я развернул приложение Rails 3.2.2 на heroku. Когда я пытаюсь получить доступ к моему приложению через браузер. У меня

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.

Итак, я начала искать в интернете, как обычно, чтобы понять, что не так. Тогда я научусь использовать в Heroku журналы чтобы проверить мой файл журнала. Вот файл журнала.

после просмотра журналов я не действительно понимаю, что не так. Я снова в Интернете. Кажется, есть много разных причин, которые могут вызвать эту проблему. Я знаю, что в моем приложении могут быть ошибки. Но я не могу сказать, какая часть моего кода неверна.

и Я могу запустить приложение на своем локальном компьютере. Так вы знаете в чем проблема или как определить проблему?

обновление:

когда я делаю git push heroku

Я получаю эту ошибку сообщение

Your bundle is complete! It was installed into ./vendor/bundle

Это случилось со мной сегодня. Это не типичное поведение, но, по-видимому, все, что мне нужно было сделать, это ругать хероку через монитор компьютера, ждать, пока он подумает о том, насколько непослушным он был, и, наконец, он исправил свое поведение.

иногда Heroku капризен?


кажется, что вы получаете тайм-аут, может быть, этот вызов feed () занимает более 30 секунд?

подробнее о кодах ошибок H12 в https://devcenter.heroku.com/articles/error-codes#h12__request_timeout. Я также рекомендую вам установить Rack-timeout, как описано вhttps://devcenter.heroku.com/articles/request-timeout.


ошибки оказались приложением.стиль CSS. Есть ошибки в одном .css.scss файлы /assets/stylesheets

когда я побежал разгребать assets:precompile на локальном mahcine он показал ошибки в application.css. Он указал, какой код применяется.CSS-это неправильно.

после того, как я пересмотрел css, и я должен поставить config.assets.initialize_on_precompile = false' inконфиг/приложения.rb' http://www.simonecarletti.com/blog/2012/02/heroku-and-rails-3-2-assetprecompile-error/

проблема решена!


У меня была аналогичная проблема, и после отказа в течение дня я вернулся к ней и нашел свою ошибку. Я не отправлял ответ клиенту, когда на стороне сервера произошла ошибка. Убедитесь, что вы возвращаете ответ независимо от результата алгоритма на стороне сервера. Если есть ошибка, верните ее. Если запрос был удовлетворен, верните ответ. Надеюсь, это поможет.

Если это не поможет, ознакомьтесь с руководствами heroku по обработке таймаутов запросов, особенно может помочь раздел таймауты запросов отладки.


У меня была очень похожая проблема и сузила ее до проблемы подключения к базе данных. Я использую ClearDB в Кедровом стеке Heroku и обнаружил, что, вставив "use ActiveRecord:: ConnectionAdapters:: ConnectionManagement" в мой config.ru файл, проблема уходит.
