【问题描述】：
由于某种原因，应用引擎有时会关闭（到目前为止，它在不同日期发生了 3 次），然后在 10 分钟后启动（手动停止和启动实例大约需要 1 分钟，所以这似乎很长）。
之前没有错误或其他指示关闭原因的日志（在关闭之前也没有 ah/stop）。
应用程序在标准应用引擎上使用 1 个实例以手动扩展模式运行。应用程序大部分时间处于“空闲”状态（它确实运行但不接收请求。）运行时是 java11。
可能是什么原因？

我遇到了同样的问题，我的应用程序（JVM 11）配置了手动缩放和 1 个实例，并且 App Engine 似乎无缘无故地定期杀死它（这不是内存问题） .但是，我的应用程序会在一两分钟内重新启动，但这足以让我收到关于我配置的正常运行时间检查的事件通知。我得到相同的“退出终止信号”和“启动程序失败：由 nginx 退出触发的终止”日志。
