Stanley Sung created HAWQ-1384:
----------------------------------

             Summary: runaway_detector_activation_percent = 100 doesn't disable runaway_detector
                 Key: HAWQ-1384
                 URL: https://issues.apache.org/jira/browse/HAWQ-1384
             Project: Apache HAWQ
          Issue Type: Bug
          Components: Query Execution
            Reporter: Stanley Sung
            Assignee: Lei Chang


When setting runaway_detector_activation_percent to 100, we still see queries canceled by
runaway_detector like the following:
ERROR:  Canceling query because of high VMEM usage. Used: 64MB, available 81856MB, red zone:
-16MB (runaway_cleaner.c:152)  (seg9 xxxxx.xxxx.xxxx:40000 pid=646507) (dispatcher.c:1801)

Note that redzone is negative and used mem is way less than available.
