问题描述
我在 Azure Web 应用 (Linux) 上部署了一个基于 .NET Core 5 的 Web 应用程序。 Web 应用的部署通过 Azure DevOps 进行，最后一次部署发生在 4 月底，没有人以任何形式接触 Web 应用。
但是，应用程序突然停止并以默认的 Azure 页面“您的应用服务已启动并正在运行”进行响应。 根据 AppInsights 的说法，该应用程序没有承受任何沉重的负载，只有少数人在 Web 上使用 cpu 和 RAM 大约 20%。 “始终开启”设置已开启。
根据下面的日志，我假设运行我的 web 应用程序的机器由于某种原因重新启动（我猜是 Azure 维护）我看到它无法找到启动所需的文件，因此它使用默认的 Azure 页面.但是，我不明白为什么文件在那里，此外，正如您在 9:52 看到的，我们通过 Azure 门户手动重新启动了 Web 应用程序并解决了问题。
我正在寻求有关防止这种行为的建议，因为这是第二次发生，第一次发生在 5 个月前。谢谢
