我们最近开始遇到一个问题,即我们所有设置为 .NET 2.0 和集成模式的应用程序池在启动时立即崩溃。
IIS 日志中没有任何内容,但 HTTPERR 日志每次都显示相同的内容:
Line 2084: 2013-11-15 01:33:39 10.71.21.242 57020 192.168.16.26 80 HTTP/1.1 GET / - 129 Connection_Abandoned_By_ReqQueue test
我已经运行了 DebugDiag 并访问了该站点,据我所知,我得到了一些相对无用的信息:
In w3wp__test__PID__5196__Date__11_14_2013__Time_03_16_34PM__253__Second_Chance_Exception_E0434352.dmp the assembly instruction at KERNELBASE!RaiseException+3d in C:\Windows\System32\KERNELBASE.dll from Microsoft Corporation has caused a CLR Exception on thread 8

我无法在此运行 WinDbg,因为在它崩溃之前我无法足够快地进入该进程。
我不确定是什么导致了这两个特定设置设置(如果我更改为 .NET 4.0 -或更改为经典模式,站点将正常工作)。
也值得注意:这与在每个应用程序池中运行的站点无关 - 它发生在 Sitecore、Umbraco 和静态站点(包括一个 hello world 应用程序)
在与 Microsoft 进行了长时间的支持请求后,结果证明这是将以下键设置为 1 的结果:
将其设置回 0 解决了这个问题。
