TcpListener最终停止接受来自GPS客户端的连接

Question

我正在使用TcpListener使用C＃开发服务器应用程序，该应用程序应该监听1000个GPS设备。当前代码正在与多个客户端连接，因此工作正常，但问题是一段时间后（可能是几小时或一天），侦听器将停止侦听客户端。有时，侦听器接受来自某些但不是全部设备的连接，有时它根本不接受任何连接。当我检查“资源监视器”时，有打开的连接并已接收数据，但新的连接未连接。

static void Main(string[] args)
{
    try
    {
        MainAsync().Wait();
    }
    catch (Exception ex)
    { }
    finally { }
}

static async Task MainAsync()
{
    Console.WriteLine("Starting...");
    var server = new TcpListener(IPAddress.Parse("IP Address"), “Port No”);

    try
    {
        server.Start();

        Console.WriteLine("Started.");
        while (true)
        {
            var client = await server.AcceptTcpClientAsync().ConfigureAwait(false);

            try
            {
                Console.WriteLine("-New Client Connected at: " + DateTime.Now.ToString());
                var cw = new ClientWorking(client, true);
                cw.ClientAsync().NoWarning();
            }
            catch (Exception ex)
            {
                client.Client.Close();
            }
            finally { }
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }

    public ClientWorking(TcpClient client, bool ownsClient)

        _client = client;
        _ownsClient = ownsClient;

            while (_client.Client.Connected)
            {
                using (var stream = _client.GetStream())
                {
                    using (var sr = new StreamReader(stream))
                    using (var sw = new StreamWriter(stream))
                    {
                        sw.FlushAsync().ConfigureAwait(false);
                        var data = default(string);
                        int i;
                        Byte[] bytes = new Byte[1024];

                        while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
                        {
                            data = ByteArrayToString(bytes);

                            string[] dt0 = Regex.Split(data, "0d0a");
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            _client.Client.Close();

        finally { }
    }
