Question

我们有一个asp.net MVC应用程序，使用Fluent Nhibernate在IIS7及其上运行Windows Sever 2008.经常（虽然到目前为止我们还没有一贯地重现它）在构建之后我们得到一个黄色的死亡屏幕，但有这个例外：

似乎其他一些people发现了同样的问题，虽然没有人似乎有解决方案，但有什么想法？

Answer 1

这听起来就像我在Windows 2008上看到的COM +和MSMQ一样。当用户注销时，无论是否有任何剩余的打开句柄，Windows 2008都会卸载用户注册表配置单元。您应该在事件日志中看到正在使用它的进程卸载配置单元的条目。

可以设置一个GPO来防止这种情况发生（DisableForceUnload）

Answer 2

这看起来像是.NET框架本身的一个错误。

请注意，innermost method being called未指定它可以抛出一个ComException。

我建议更新到Castle Dynamic Proxy（2.2 beta）的最新版本，看看问题是否仍然存在。

如果是，您可以尝试使用其他代理提供商之一。

并将此问题报告给Microsoft Connect
