Seeding a torrent that uses both ws and udp on the same tracker crashes the tracker

[gmbuell]

I can't reproduce this using tracker.webtorrent.io since I can't seem to connect using udp. However, when running a local tracker with this client code:

var torrent = client.seed(filePath, {
    announceList: [['udp://mytracker:8000',
                    'ws://mytracker:8000']]
});

Crashes the tracker with

/usr/local/lib/node_modules/bittorrent-tracker/server.js:314
        peer.socket.send(JSON.stringify({
                   ^

Thanks for the report. I think I know what's causing this.

Okay, this is fixed in the latest bittorrent-tracker, v4.4.4.

And the UDP server is running on tracker.webtorrent.io again :)
