How to judge the limit number of query tasks mentioned in the system message of Apache IoTDB?

Apache IoTDB system reported "the system can't allow more query tasks". I understand that this means the query amount is too much to execute, but I want to ask how this query task limit is judged, through which parameter? Also, how can I check the number of tasks mentioned in this error to avoid this being popped out again?

You can use show queries statement to take a look at all the query tasks happening in Apache IoTDB. Generally, this error should be caused by the number of concurrent queries exceeds the setting of max_allowed_concurrent_queries. You can use this way to check the number of query tasks you have and reset the max_allowed_concurrent_queries parameter value if you need.
