Yeah, the ~1000 socket limit is a system issue and completely unrelated to
mono. It's the assert that is more interesting.

I still get the assert failure, just to make sure you're running the right
testcase, execute the attached testcase and just wait a few seconds once you
hit the Console.ReadLine (). Don't press a key.



using System;
using System.Net;
using System.Net.Sockets;
using System.Collections.Generic;

namespace Test
{
    class MainClass
    {
        static List<Socket> list = new List<Socket>();
        public static void Main(string[] args)
        {
            TcpListener listener = new TcpListener(10000);
            listener.Start(1);
            for (int i = 0; i < 100000; i++)
            {
                try
                {
                    Socket s = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);
                    IAsyncResult result = s.BeginConnect(IPAddress.Loopback,
10000, null, null);
                    list.Add(listener.AcceptSocket());
                    s.EndConnect(result);
                    list.Add(s);
                }
                catch (SocketException ex)
                {
                    if (ex.ErrorCode == 10024)
                    {
                        Console.WriteLine("Instantiate {0} sockets",
list.Count);
                        Console.WriteLine(ex);
            Console.ReadLine ();
                        return;
                    }
                }
            }

            Console.WriteLine("Success");
        }
    }
}
