I'm not using Airflow although I'm running long running task with late ack,
the rest of the options are:
```
worker_prefetch_multiplier = 1
worker_concurrency = int(os.environ.get("WORKER_CONCURRENCY", 1))
worker_max_tasks_per_child = 1
worker_send_task_events = True
worker_redirect_stdouts = False
worker_cancel_long_running_tasks_on_connection_loss = True
task_send_sent_event = True
task_ignore_result = False
task_serializer = "json"
task_acks_late = strtobool(os.environ.get("CELERY_ACKS_LATE", "True"))
task_always_eager = strtobool(os.environ.get("CELERY_EAGER", "False"))
task_eager_propagates = True # if eager == True the this applies
task_track_started = True
task_time_limit = 86400 * 2 # 48 hours in seconds
```
I'm requesting to cloudamqp a cluster downgrade in the meantime to 3.8.14
while we can clarify a solution from the application side and/or an increase in
the consumer_timeout parameter.
