>             Project: ZooKeeper
>          Issue Type: Bug
>            Reporter: prashant
>
> three issues 
> 1)zoo_aremove_watchers() does not remove a watch if path has more than one watch.
> but it works in below cases.
> it removes watch if path has only one watch.
> and it removes all watches if watcher function arguments is NULL.
> Seen in 
> zookeeper.version=3.5.1-alpha--1, built on 06/09/2016 18:31 GMT
> Not sure if this is fixed in later versions.
> 2) If zoo_aremove_watchers()  is called with local=1, then client hangs in waiting for mutex in mt_adaptor.c:102
> void notify_sync_completion(struct sync_completion *sc)
> {
>     pthread_mutex_lock(&sc->lock);
> ...
> 3) Acts like sync API if no node and no watcher on path.
> it does not call async completion callback in this case.
