[jira] Commented: (ZOOKEEPER-795) eventThread isn't shutdown after a connection session expired event coming
[ https://issues.apache.org/jira/browse/ZOOKEEPER-795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=12897853#action_12897853 ] Patrick Hunt commented on ZOOKEEPER-795: This is blocking a release candidate for 3.3.2, if we can get this in soon I'll start running through the release process. 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.

When we fix this we should also address the event thread naming.
