Unity TCP server freezing - unity3d

Question

I'm trying to get tcp server working in unity, and it's kinda working. My systems purpose is to read data from another program that sends me bytes and draws me a picture of that data. Main problem is that when I run it, it works for a while (random time) and then whole unity freezes and I need to kill it from the task manager.
void Start()
{
Display1 = gameObject.GetComponent<Renderer>();
mymat = GetComponent<Renderer>().material;
packetReady = false;
tcpListenerThread = new Thread(new ThreadStart(ListenForIncommingRequests));
tcpListenerThread.IsBackground = true;
tcpListenerThread.Start();
bytes = new byte[1024];
tex = new Texture2D(800, 1280, TextureFormat.RGB24, false);
firstTime = true;
ArrayInit(3072060);
packetLength = 3072060;
myThread = new Thread(Draw);
myThread.Start();
}
void Draw()
{
if (Loader == null)
{
return;
}
else if (packetReady)
{
tex.LoadRawTextureData(Loader);
tex.Apply();
mymat.SetTexture("_EmissionMap", tex);
Display1.material.mainTexture = tex;
packetReady = false;
}
}
void Update()
{
Draw();
}
private void ListenForIncommingRequests()
{
try
{
tcpListener = new TcpListener(IPAddress.Parse("127.0.0.1"), 35800);
tcpListener.Start();
while (true)
{
if (!tcpListener.Pending())
{
Thread.Sleep(100);
}
Thread.Sleep(10);
using (connectedTcpClient = tcpListener.AcceptTcpClient())
{
using (NetworkStream stream = connectedTcpClient.GetStream())
{
int length;
while ((length = stream.Read(bytes, 0, bytes.Length)) != 0)
{
if (bytes == null)
{
return;
}
else
{
ParseData(bytes);
}
}
}
}
}
}
catch (SocketException socketException)
{
Debug.Log("SocketException " + socketException.ToString());
}
finally
{
tcpListener.Stop();
}
}
I have no idea what is causing this, I've tried to solve the problem but nothing seems to work. Any suggestions?
