Can you do a little test ?? Just modify the RecordProtocol.ReceiveRecord 
method as:

       public byte[] ReceiveRecord()
       {
           if (this.context.ConnectionEnd)
           {
               throw new TlsException(
                   AlertDescription.InternalError,
                   "The session is finished and it's no longer valid.");
           }

           // If the inner stream is a NetworkStream and there are no data
           // return null
           if (this.context.IsActual && this.innerStream is NetworkStream)
           {
               if (!((NetworkStream)this.innerStream).DataAvailable)
               {
                   return null;
               }
           }

           ...
      }

And let us now if that helps. If not, can you send a test case 
reproducing the problem ??
