IIS 应用程序池不断崩溃

【问题标题】：IIS app pool keeps crashingIIS 应用程序池不断崩溃
【发布时间】：2017-03-14 15:16:50
【问题描述】：

我们的应用程序池莫名其妙地不断崩溃，并且我已禁用快速故障-故障保护，因此我们的网站不会关闭，但这并不是找到错误的真正方法。

事件日志中包含以下错误： 为应用程序池（名称）提供服务的进程与 Windows 进程激活服务发生了致命的通信错误。进程 ID 为“8480”。数据字段包含错误号。

我已经对它何时崩溃进行了 DebugDialog 分析，但这并没有告诉我什么？

    【解决方案1】：

    我发现了如何获得更详细的堆栈跟踪。 我下载了在 Windows 软件开发工具包中找到的 Windbg：https://developer.microsoft.com/da-dk/windows/hardware/windows-driver-kit

    在 Windbg 中打开故障转储文件并运行以下命令：

    .loadby sos.dll clr
!clrstack

    这将为您提供更详细的问题堆栈跟踪。 在这种情况下，它是一个反复调用的函数。
