UDP packet loss #4199

Hi.
My Node app doesn't send some UDP packets.
It happens on different versions of Node (5.1.1, 0.10.x) and on different OSes (Win 10 and Raspbian (RPI Debian)).

Here's the one for reproduction:

var dgram = require("dgram");
var udpServer = dgram.createSocket("udp4");
var port = 14000;
var host = '172.16.0.7';

function send(data) {
>//console.log('s', data);
>udpServer.send(data, 0, data.length, port, host);
};

setInterval(function(){
for (var i=0; i<33; i++) {
send(new Buffer("fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff"));
}
}, 1000);

I guess it is the same issue: nodejs/node-v0.x-archive#6696

Wireshark shows that not all packets are sent, for example sequence ID of next packet can be bigger on 5 or even 15.
