Jialin Qiao created IOTDB-2058:
----------------------------------

             Summary: Query is blocked without sub-query-threads exist
                 Key: IOTDB-2058
                 URL: https://issues.apache.org/jira/browse/IOTDB-2058
             Project: Apache IoTDB
          Issue Type: Bug
    Affects Versions: 0.12.3
            Reporter: Jialin Qiao
            Assignee: Alima777
         Attachments: image-2021-11-25-14-36-27-927.png, jstack.txt

In an IoTDB Instance, the query main thread is blocking. We could see the queryId using show query proceslist. However, we couldn't see the sub query thread of the blocked query in the jstack file.

This may be due to that the sub-thread is dead because some error（not catched by Exception）
