app.celery.ContextTask.acks_on_failure_or_timeout
- ContextTask.acks_on_failure_or_timeout = True
When enabled messages for this task will be acknowledged even if it fails or times out.
Configuring this setting only applies to tasks that are acknowledged after they have been executed and only if :setting:`task_acks_late` is enabled.
The application default can be overridden with the :setting:`task_acks_on_failure_or_timeout` setting.
