>             Project: ZooKeeper
>          Issue Type: Improvement
>          Components: c client, java client
>    Affects Versions: 3.4.5, 3.4.6
>         Environment: jdk1.7_45 on centos6.5 and ubuntu14.4 
>            Reporter: Caspian

> I use zk to  monitor the children nodes under a path, eg: /servers. 
> when the client is told that children changes,  I have to re-watch the path again, during the peroid, it's possible that some children down, or some up. And those events will be missed.
> For now, my temporary solution is not to use getChildren(path, true...) to get children and re-watch this path, but re-watch this path first, then get the children. Thus non events can be ignored, but I don't know what will the zk server be like if there are too much clients that act like this.
> How do you think of this problem? Is there any other solutions?
