[jira] [Created] (CURATOR-654) DistributedBarrier watcher leak

Stuart Scott created CURATOR-654:
------------------------------------

             Summary: DistributedBarrier watcher leak
                 Key: CURATOR-654
                 URL: https://issues.apache.org/jira/browse/CURATOR-654
             Project: Apache Curator
          Issue Type: Bug
          Components: Recipes
    Affects Versions: 5.3.0
            Reporter: Stuart Scott


The DistributedBarrier adds a zookeeper exists watcher in the waitOnBarrier() method. It appears as though the watcher is never removed. In a system where DistributedBarriers are used heavily this eventually results in the system running out of memory.
