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.
