Worker died (ID: 3, PID: 8080), port: undefined

The problem is that, at least for me, the worker variable inside the cluster.on.exit event doesn't have a port attribute... so when calling the fork_worker(worker.port), it passes as undefined.

I fixed it by adding it as an atribute right after creating the worker on the fork_worker. Maybe that can help someone out there.

var fork_worker = function(port)
{
    var worker = cluster.fork({worker_port: port});
    worker.port = port;
};
