[3507] An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full

[Arno den Uijl]

When opening a massive amount of sessions from the .net client I get a socketexception in 3507. In de stable 2.5 release this doesn't happen.

One could argue you shouldn't open as many sessions, but since 2.5 doesn't break i would expect 3.0 wouldn't either. 

The exception:

Unhandled Exception: System.AggregateException: One or more errors occurred. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full

Code to reproduce:

using System;

using System.Threading.Tasks;

using Raven.Client.Document;

namespace ConsoleApplication3

{

    class Program

    {

        static void Main(string[] args)

        {

                var store = new DocumentStore {Url = "http://localhost:8080", DefaultDatabase = "test"}.Initialize();

                Parallel.For(0, 100000, new ParallelOptions() {MaxDegreeOfParallelism = Environment.ProcessorCount}, i =>

                {

                    using (var ses = store.OpenSession())

                    {

                        ses.Store(new

                        {

                            Id = "test/" + i,

                            Naam = "Name"

                        });

                        ses.SaveChanges();

                        var a = ses.Load<dynamic>("test/" + i);

                    }

                });           

        }

    }

}
