Mahadev konar commented on ZOOKEEPER-795: ----------------------------------------- ben, pinging again, can you provide a patch for 3.3.2? > eventThread isn't shutdown after a connection "session expired" event coming > ---------------------------------------------------------------------------- > > Key: ZOOKEEPER-795 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-795 > Project: Zookeeper > Issue Type: Bug > Components: java client > Affects Versions: 3.3.1 > Environment: ubuntu 10.04 > Reporter: mathieu barcikowski > Assignee: Sergey Doroshenko > Priority: Blocker > Fix For: 3.3.2, 3.4.0 > > Attachments: ExpiredSessionThreadLeak.java, ZOOKEEPER-795.patch, > ZOOKEEPER-795.patch > > > Hi, > I notice a problem with the eventThread located in ClientCnxn.java file. > 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.
