I finally solved it!

I added:

io.removeAllListeners();

Right below:

io.on('connection', function(socket){

So now it looks like this:

io.on('connection', function(socket){
        io.removeAllListeners();
        console.log('a user connected: ' + socket.id);
        r.table('Groups')
            .filter(r.row("members")
            .contains(req.user['id']))
            .changes({ includeInitial: true })
            .run()
            .then(function(feed){
                 feed.each(function(err, item){
                  console.log(req.user['entra']);
                //console.log(JSON.stringify(item, null, 2));

                socket.emit('group',item.new_val);
             })
          })
   });

And it works and I don't get multiple messages / console.logs or emits anymore.
