I meet the same problem. I registe the error handler like this:

	mysocketio.OnError("", func(err error) {
		log.Errorf("error=%+v", err)
		ctrl.DealError("", err)
	})

// ... github.com/googollee/go-socket.io/conn.go:142~154
func (c *conn) serveError() {
	defer c.Close()
	for {
		select {
		case <-c.quitChan:
			return
		case msg := <-c.errorChan:
			if handler := c.namespace(msg.namespace); handler != nil {
				handler.onError(msg.error)
			}
		}
	}
}

When error event is triggered, I can get the call stack, but I don't known which Conn this error beyond to.
