System.ServiceModel.CommunicationException: la connexion sous-jacente a été fermée

Je suis de la récupération de données à partir d'un service web wcf et lorsque les données sont de plus de 0,2 million d'enregistrements, j'obtiens une exception qui est la suivante:

System.ServiceModel.CommunicationException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. ---> System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

De mon site web.config ressemble à ceci :

<basicHttpBinding>

</binding>
</basicHttpBinding>

Je suis sûr que mon service web est en train de récupérer des données à partir de DB. mais il est impossible de transférer mon site web à partir d'où j'ai lancé l'appel. Merci d'avance pour toute aide.
