      Description

      I set small queue to allow only 1 concurrent query:
      alter system set `exec.queue.enable`=TRUE;
      alter system set `exec.queue.small`=1;

      When running 2 small queries, one of them is pending which is expected.
      (See pic 1)

      ​After about 5mins(exec.queue.timeout_millis), the pending SQL starts. now we have 2 queries running in small queue.
      (See pic 2)
