Heroku 上的 H12 超时错误

Question

谁能解释导致 Heroku 出现此超时错误的原因（2012-07-08T08:58:33+00:00）？文档说这是因为一些长期运行的过程。我在 config/application.rb 中设置了config.assets.initialize_on_precompile = false。

具体错误：

2012-07-08T08:58:33+00:00 heroku[router]: 错误 H12（请求超时）-> GET codicology.co.uk/dyno=web.1 queue=wait= service=30000ms status= 503 字节=0

heroku[router]: Error H12 (Request timeout) -> GET codicology.co.uk/dyno=web.1 queue= wait= service=30000ms status=503 bytes=0

在您的应用部署期间，您是否从codicology.co.uk 加载某些内容？例如加载托管在那里的自定义构建包？

如果我访问 codicology.co.uk，我会收到证书错误。也许您从 Heroku 运行的任何进程或请求都会收到证书错误，这也会阻止它正确连接，或者它可能会因为错误而决定断开连接。

如果您可以向我们提供更多信息，了解您正在尝试做什么或 codicology.co.uk 的用途（您拥有它吗？）也许我们可以提供更多帮助。
