由于线程退出或应用程序请求，I/O 操作已中止

Question

我正在一个高流量网站上运行一些 WCF net.tcp 服务。 在我当地的环境中，一切都按预期进行。 在生产环境中，网站运行几分钟，然后服务抛出异常。 当我停止并重新启动服务网站时，它会再次运行几分钟。

详情如下：

传输数据时发生 TCP 错误（995：I/O 操作已因线程退出或应用程序请求而中止）。

System.ServiceModel.Channels.SocketConnection.EndRead() System.ServiceModel.Channels.TracingConnection.EndRead() System.ServiceModel.Channels.ConnectionStream.ReadAsyncResult.OnAsyncReadComplete（对象状态） System.ServiceModel.Channels.TracingConnection.TracingConnectionState.ExecuteCallback() System.ServiceModel.Channels.SocketConnection.AsyncReadCallback（Boolean haveResult，Int32 错误，Int32 bytesRead） System.Runtime.Fx.IOCompletionThunk.UnhandledExceptionFrame（UInt32 错误，UInt32 bytesRead，NativeOverlapped* nativeOverlapped） System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOVERLAP)

我在 Win8kR2SP1Web 上看到了同样的问题：
