我为我的客户管理一个rails应用程序,最近它崩溃了.在我发现之前,该网站已经停机了9个小时.我检查了日志,过去9小时的每个请求都附加了以下代码：

at=error code=H10 desc="App crashed"

在此之前,我看到以下日志：

我猜它可能已经旋转并且有一个错误启动备份,但为什么它没有重新启动它仍然处于崩溃状态？如果将来再次发生这种情况,有什么办法可以让它自动重启吗？

我也有NewRelic在这上面运行它根本没有通知我,但这是我必须调查的另一个问题.

解决方法

Heroku的支持回答建议使用heroku restart手动重启你的应用程序.他们现在正在解决这个问题.

Hi,A process management error on our side caused some crashed apps only running 1 web dyno to be reported as “idle” even though they were actually crashed. This means that the crashed dyno was never restarted,causing subsequent requests to fail. We’ve identified this problem and are implementing a fix. If your app is still unresponsive,please try restarting it with the heroku restart command. Please let us know if you need more help. Thanks,Heroku Support
