The I/O operation has been aborted because of either a thread exit or an application request

Question

I'm running some WCF net.tcp services on a high-traffic website. In my local environment everything worked as expect. In the production environment, the website works for few minutes then the service throw an exception. When I stop and start again the service website it works again for few minutes.

Here's the details:

A TCP error (995: The I/O operation has been aborted because of either a thread exit or an application request) occurred while transmitting data.

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

Answer 1

I see the same problem on Win8kR2SP1Web:

System.Runtime.InteropServices.COMException (0x800703E3): The I/O operation has been     aborted because of either a thread exit or an application request. (Exception from HRESULT: 0x800703E3)
An error occurred while communicating with the remote host. The error code is 0x800703E3.
The I/O operation has been aborted because of either a thread exit or an application request. (Exception from HRESULT: 0x800703E3)
