Getting System.ServiceModel.ProtocolException while Consuming WCF Webservice

Question

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 System.ServiceModel.Channels.HttpInput.ReadBufferedMessage(Stream inputStream) at System.ServiceModel.Channels.HttpInput.ParseIncomingMessage(Exception& requestException) at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout) at System.ServiceModel.Channels.RequestChannel.Request(Message message, TimeSpan timeout) at System.ServiceModel.Dispatcher.RequestChannelBinder.Request(Message message, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) at IBulkDataSvc.GetEmployeesData(String BusinessPath, DateTime EffectiveDate, String TerminalName) at Empower.ServiceRequest.EmployeeDataXML(DateTime time, String terminal) at Empower.Empower.DownloadEmployeeList(String terminalName)

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?

I have googled and did not fine anything much helpful.So can some one please help me out from this puzzle .

Did you enable logging in the WCF services to analyze. This alone can give better insights into the issue you are running into now. Analysis of the log file can help you. Or post the exception detail from the svclog file for us. — Saravanan

Have you got a chance to read this calling non wcf service

Also, in some cases iF your request is bringing data larger than what is specified at webservice side then you are bound to get this.
