Subject [jira] [Commented] (CURATOR-153) PathChildrenCache occasionally cannot reconnect to ZK
Date Mon, 13 Oct 2014 19:58:33 GMT

I found the bug!!! It can occur in a special case of connection loss. When that happens a
new event is created and this event might get incorrectly sent to the PathChildrenCache. I'll
work on a fix.
