My Heroku-hosted (ruby Sinatra) app has worked perfectly for the last month without me changing it, but today the app error'd while trying to start up after idling:

2013-02-08T15:44:34+00:00 heroku[web.1]: Idling
2013-02-08T15:44:38+00:00 heroku[web.1]: Stopping all processes with SIGTERM

After a few more minutes of error codes, the app tried to unidle again and did so successfully. Any idea what caused this and how I could prevent it from happening again?

H20 错误通常意味着您的应用在空闲后需要很长时间才能启动。Heroku Dev Center中有详细信息。正如开发中心建议的那样，您可能应该检查资产是否已预编译，或者是否有其他可能会减慢应用程序启动速度的事情。
