Tcp socket is closing after some iterations of while(true)[C#]

I have a client which connects to server with 3 connections and server is receiving all the data from these connections but after some processing in the client side server detects that these 3 connections are disconnected. I tried executing the code line by line and found out that after running around 13 iterations of while(true) the client disconnects itself. The code in the while loop has nothing to do with the sockets.

What I have tried:

Function to connect to server

public static void ConnectToServer()
        {
            byte[] request = Encoding.ASCII.GetBytes("Add Connection|requestSplit" + Environment.MachineName + "|requestSplit|requestSplitLive Screen");
            Socket s = clientSocket.socketConnect();
            sendToServer.SendFullData(request, s);

            Console.WriteLine("Connected: " + s.RemoteEndPoint);
            logFileWrite(DateTime.Now.ToString("hh:mm:ss") + ": " + Encoding.ASCII.GetString(request));

            Thread.Sleep(1000);

            request = Encoding.ASCII.GetBytes("Add Connection|requestSplit" + Environment.MachineName + "|requestSplit|requestSplitAudio");
            s = clientSocket.socketConnect();
            sendToServer.SendFullData(request, s);

            Console.WriteLine("Connected: " + s.RemoteEndPoint);
            logFileWrite(DateTime.Now.ToString("hh:mm:ss") + ": " + Encoding.ASCII.GetString(request));

            Thread.Sleep(1000);

            request = Encoding.ASCII.GetBytes("Add Connection|requestSplit" + Environment.MachineName + "|requestSplit|requestSplitPath");
            s = clientSocket.socketConnect();
            sendToServer.SendFullData(request, s);

            Console.WriteLine("Connected: " + s.RemoteEndPoint);
            logFileWrite(DateTime.Now.ToString("hh:mm:ss") + ": " + Encoding.ASCII.GetString(request));

            Thread.Sleep(1000);

            Console.WriteLine("Connected");
        }

while loop:

Thread restrictedAreaThread = new Thread(restrictedAreasAccess);
restrictedAreaThread.IsBackground = true;
restrictedAreaThread.Start();

private void restrictedAreasAccess()
{
      int count = 1;
      while(true)
      {
          SHDocVw.ShellWindows shellWindows = new SHDocVw.ShellWindows();
          foreach (SHDocVw.InternetExplorer ie in shellWindows)
          {
               filename = Path.GetFileNameWithoutExtension(ie.FullName).ToLower();
               if (lastPathAccessed != ie.LocationURL)
               {
                  if (filename.Equals("explorer"))
                  {
                      // Save the location off to your application
                      filenameArray.Add(DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss") + "-" + ie.LocationURL);

                      if (ie.LocationURL != null || ie.LocationURL != string.Empty)
                      {
                         // Setup a trigger for when the user navigates
                         try
                         {
                            string unread = "Unread";
                            string pathAccessedDB = cpuInfo + " - pathAccessed";
                            string query = string.Empty;

                            string urlString = ie.LocationURL.ToString();
                            if (urlString.Contains("\\"))
                            {
                                urlString = urlString.Replace("\\", "/");
                            }
                            if (urlString.Contains("%20"))
                            {
                                urlString = urlString.Replace("%20", " ");
                            }
                            if (urlString.Contains("file:///"))
                            {
                                urlString = urlString.Replace("file:///", string.Empty);
                            }
                            Console.WriteLine("Filter: " + urlString);

                            try
                            {
                                string ConnectionString = @"Server=" + Program.server + ";Database=monitoringsystem;port=3306;uid=" + Program.userid + ";pwd=" + Program.password + "";
                                MySqlConnection connection = new MySqlConnection(ConnectionString);
                                connection.Open();
                                MySqlCommand command = new MySqlCommand();
                                command.Connection = connection;
                                command.CommandText = "insert into `" + pathAccessedDB + "`(TimeStamp, Path, Status) values('" + DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss").Replace("'", "''") + "','" + urlString.ToString() + "','" + unread + "')";
                                query = command.CommandText;
                                command.ExecuteNonQuery();
                                connection.Close();

                                lastPathAccessed = ie.LocationURL;
                             }
                             catch (Exception ex)
                             {
                                MessageBox.Show(ex.ToString() + "\nFor query: " + query);
                             }
                       }
                       catch (Exception ex)
                       {
                          MessageBox.Show(ex.ToString());
                       }
                   }
                   else
                   {
                     Console.WriteLine("Location is null!");
                   }
              }
           }
        }
    }
}

In the restrictedAreasAccess() after 13 iterations the server detects client disconnection. If I comment the call function then the program works correctly. I don't know what is wrong with this.
