[jira] [Created] (ROCKETMQ-290) Memory leaks in org.apache.rocketmq.store.ha.WaitNotifyObject#waitingThreadTable

Jason Jiang created ROCKETMQ-290:
------------------------------------

             Summary: Memory leaks in org.apache.rocketmq.store.ha.WaitNotifyObject#waitingThreadTable
                 Key: ROCKETMQ-290
                 URL: https://issues.apache.org/jira/browse/ROCKETMQ-290
             Project: Apache RocketMQ
          Issue Type: Bug
          Components: rocketmq-store
    Affects Versions: 4.1.0-incubating
            Reporter: Jason Jiang
            Assignee: yukon
            Priority: Critical


There are only add-element operations for waitingThreadTable in Class org.apache.rocketmq.store.ha.WaitNotifyObject.

Each time a new thread calls Method WaitNotifyObject#allWaitForRunning, waitingThreadTable get new element. 

This leak actually happens in Master Broker when Slave reconnect to the Master, a new HAConnection is created, and WaitNotifyObject#allWaitForRunning will be called in LogHAConnection.WriteSocketService#run.
