Beanstalk应用程序随机从正常状态变为严重状态

【以下的问题经过翻译处理】 我发现最近两个晚上我的EB应用程序一直崩溃。我一直收到来自AWS的错误邮件：

Environment health has transitioned from Ok to Severe. None of the instances are sending data.

当这种情况发生时，我会收到来自AWS的电子邮件警报，告知我服务器已停止，但我无法进行任何更改或请求日志，因为我此时应用程序处于无效状态。我一直在重启我的EC2实例，似乎解决了问题，但这可能是一个偶然的结果。

在服务器上有一个Python / Django应用程序。
