WaWorkerHost.exe 崩溃角色：CallbackException

当我在 Azure 上运行 WorkerRole C# 应用程序时，一段时间后 waworkerhost.exe 由于以下异常而崩溃：

Application: WaWorkerHost.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Runtime.CallbackException
Stack:
   at System.Runtime.Fx+IOCompletionThunk.UnhandledExceptionFrame(UInt32, UInt32, System.Threading.NativeOverlapped*)
   at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32, UInt32, System.Threading.NativeOverlapped*)

我有一个为 Web 服务器生成负载的应用程序。我不关心实际响应，但我想控制每秒发出的请求数。因此，我有一个每秒触发一次并生成多个请求的计时器。我尝试了以下选项：

Parallel.For 与 WebRequests
For 循环与 ASync WebRequests
For 循环与 ThreadPool.QueueUserWorkItem(do webrequest)

当请求数量增加时，会出现异常（8+ req/sec）。所有三个选项都有相同的例外。当我在本地 DevelopmentFabric 中运行该角色时，所有三个选项都工作得很好。如果有人能给我一些关于可能出现问题的指示，我将不胜感激。如果您有其他想法从 Azure 和 C# 生成此类负载，请分享您的想法。

When I run my WorkerRole C# application on Azure, after a while waworkerhost.exe crashes due the following exception:

Application: WaWorkerHost.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Runtime.CallbackException
Stack:
   at System.Runtime.Fx+IOCompletionThunk.UnhandledExceptionFrame(UInt32, UInt32, System.Threading.NativeOverlapped*)
   at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32, UInt32, System.Threading.NativeOverlapped*)

I have an application that generates load to a webserver. I don't care about the actual response, but i want to control the number of requests made per second.
Therefore i have a Timer that fires every second and generates a number of requests. I have tried the following options:

Parallel.For with WebRequests
For loop with ASync WebRequests
For loop with ThreadPool.QueueUserWorkItem(do
webrequest)

When the number of requests increase, the exception occurs (8+ req/sec). The same exception for all three options. When I run the role in local DevelopmentFabric all three options work just fine. If someone could give me some pointers on what might be going wrong I appreciate it. If you have other ideas to generate this type of load from Azure and C#, please share your thoughts.

问题解决了，我的 WorkerRole 保持健康。
