Socket read issue on long running primary interface

Technical Questions Robot Communication

Hi guys,
I’ve implemented the primary interface protocol in C# for reading robot infos.
I’m in trouble with a long running socket read. After a few tens of minutes the connection is interrupted, generating an exception on NetworkStream.Read command:

System.IO.IOException: Impossibile leggere dati dalla connessione del trasporto: Impossibile stabilire la connessione. Risposta non corretta della parte connessa dopo l'intervallo di tempo oppure mancata risposta dall'host collegato. ---> System.Net.Sockets.SocketException: Impossibile stabilire la connessione. Risposta non corretta della parte connessa dopo l'intervallo di tempo oppure mancata risposta dall'host collegato
   in System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)

This is my snippet C# code:

var TcpConnection = new TcpClient();
TcpConnection.ReceiveBufferSize = 1024 * 32;// ; Int32.MaxValue;
TcpConnection.ReceiveTimeout = 6000;
TcpConnection.SendTimeout = 6000;
TcpConnection.ExclusiveAddressUse = true;
TcpConnection.NoDelay = true;
TcpConnection.Connect("192.168.0.5", 30001);
var s = TcpConnection.GetStream();
s.ReadTimeout = 5000;
s.WriteTimeout = 5000;
var byte[] b = new byte[1024 * 32];
while(true) {
  var streamLenght  = s.Read(b, 0, b.Length);

  // ... PARSING PACKETS HERE ...

  Thread.Sleep(50);
}

Any help?
Thanks
