Why C# Console Application Stops Working?

Question

I wrote a console application that creates a socket and listen for incoming packets on a specific port, extract them and run some sql commands for each packet. The packets are coming from over 400 devices (Data Loggers) over a private APN. so basically this program is a TCP listener, note that there are a lotta data coming, devices send data every 5 minutes plus any kinda event that needs to be sent, more than 135000 per day to be more precise.

My problem is that after a while the program crashes without any errors (program stopped working error!). This happens once or twice a month. now I wanna ask is there a way that I can reopen this console application after it crashes ?! or any other advice would be appreciated. I'm using windows server 2016

here's a bit of the code:

program.cs

using System.Collections.Generic;
using System.Linq;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
using MySql.Data.MySqlClient;

using System.IO;

{

    /*
    * some date configuration and variable declaration codes...
    */

    TcpListener serverSocket = new TcpListener(System.Net.IPAddress.Any, 9191);
    TcpClient clientSocket = default(TcpClient);

    serverSocket.Start();

    Console.WriteLine(" >> " + "Server Started @  " + ymd_out[0].ToString() + "-" + ymd_out[1].ToString() + "-" +
            ymd_out[2].ToString() + " " + m_hour + ":" + m_min + ":" + m_sec + " -> v4.4 Sakhaei 19.11.03");

    while (true)
    {
        try
        {
            clientSocket = serverSocket.AcceptTcpClient();
            ip_address = clientSocket.Client.RemoteEndPoint.ToString().Split(new char[] { ':' }, StringSplitOptions.RemoveEmptyEntries).ToArray()[0];

            /*
            * some code to basically validate the sender...
            */

            handleClinet client = new handleClinet();
            client.startClient(clientSocket, 0, clientSocket.Client.RemoteEndPoint.ToString().Split(new char[] { ':' }, StringSplitOptions.RemoveEmptyEntries).ToArray()[0], !false);
            if (num_conn > 50)
            {
                Console.Clear();
                num_conn = 0;
            }
        }
        catch (Exception e)
        {
            /*
            *  closing the port, and again openning it whenever an exception happens
            */
            clientSocket.Close();
            serverSocket.Stop();

            serverSocket = new TcpListener(System.Net.IPAddress.Any, 9191);
            clientSocket = default(TcpClient);
            serverSocket.Start();
        }
    }

    clientSocket.Close();
    serverSocket.Stop();
    Console.WriteLine(" >> " + "exit");
    Console.ReadLine();
