Alima777 created IOTDB-5712:
-------------------------------

             Summary: Concurrent bug in memory pool caused by identitySink
                 Key: IOTDB-5712
                 URL: https://issues.apache.org/jira/browse/IOTDB-5712
             Project: Apache IoTDB
          Issue Type: Bug
            Reporter: Alima777
            Assignee: Alima777


Alls sinkChannels of identitySink shares the planNodeId of identitySinkNode. Therefore, when the first child closes the sharedTsBlockQueue, it will try to clear the queryMemoryMap related about planNodeId. However, the second child can reserve, free or clear the queryMemoryMap of the same planNodeId concurrently.
