The eventThread isn't shutdown after a connection session expired event coming (i.e. never receive EventOfDeath). When a session timeout occurs and the session is marked as expired, the connexion is fully closed (socket, SendThread...) expect for the eventThread. As a result, if i create a new zookeeper object and connect through it, I got a zombi thread which will never be kill (as for the previous zookeeper object, the state is already close, calling close again don't do anything). So everytime I will create a new zookeeper connection after a expired session, I will have a one more zombi EventThread. How to reproduce : - Start a zookeeper client connection in debug mode - Pause the jvm enough time to the expired event occur - Watch for example with jvisualvm the list of threads, the sendThread is succesfully killed, but the EventThread go to wait state for a infinity of time - if you reopen a new zookeeper connection, and do again the previous steps, another EventThread will be present in infinite wait state -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
