Can not get event channel from the channel returned by Connect

[machelcheng]

Hi, i just meet a problem, I get event from channel returned by Connect failed. my code is like this:

conn, session, err := zk.Connect(....) go func() { for { event, ok := <-session if !ok { log.Errorf("fail to get session event") os.Exit(-1) }

When will I get event from session failed？
