C# – Getting System.ServiceModel.ProtocolException while Consuming WCF Webservice

I am consuming a WCF web service to which i have no control in web service side.

I have given a auto generated svc.cs proxy file by which i am consuming it.

Actually i am requesting to the web service to download some large data from client side.

Sometimes i am getting

System.ServiceModel.ProtocolException

in my Client side.

Exception is as follow:

System.ServiceModel.ProtocolException: The number of bytes available
is inconsistent with the HTTP Content-Length header. There may have
been a network error or the client may be sending invalid requests.

Server stack trace: at

My web service binding config in client side is as follow(only showing bindings),

    <bindings>
      <basicHttpBinding>
        <binding name="BulkDataSvcSoap">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Basic" />
          </security>
        </binding>
        <binding name="BulkDataSvcHttpsSoap">
          <security mode="Transport">
            <transport clientCredentialType="Basic" />
          </security>
        </binding>
      </basicHttpBinding>
      <netTcpBinding>
        <binding name="BulkDataSvcTcp">
          <security mode="None" />
        </binding>
      </netTcpBinding>
    </bindings>

I am little bit of confused from which end it is really generated and why it is generating?
