["Patrick Hunt (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ZOOKEEPER-1433?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Patrick Hunt updated ZOOKEEPER-1433:
------------------------------------

    Fix Version/s:     (was: 3.3.5)
                   3.5.0
                   3.4.4
                   3.3.6
         Assignee: Patrick Hunt

Looks like I missed checking that the clients disconnect, then reconnect after restarting the server. In some cases this doesn't happen fast enough and the exist check fails as a result (ie the client hasn't noticed that the server went down/came back).
