WCF service shutting down

Question

Hi,
i have been trying to access WCF service function(Which loads C++ Dll's too) in a C# client project.
When ever i start client program it fetches the service, loads the dll, but suddenly WCF service will be terminated from the system tray.
I have added timeout parameters in web.config(Service) and app.config(Client).
i have tried to log the error as said
here but still its not logging the errors.
what's causing this error, any help will be appreciated.
Regards,
Jithendra

I have added try/Catch in server side as well the exception that throws is as below.
System.ServiceModel.CommunicationException was unhandled
_HResult=-2146233087
_message=An error occurred while receiving the HTTP response to http://localhost:50368/Service1.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
