мой поток воздуха работает в режиме CeleryExecutor + progre sql 12, все вещи go хорошо, кроме случаев, когда включена статистика:
statsd_on = True
statsd_host = localhost
statsd_port = 8125
statsd_prefix = airflow
Планировщики могут отображать задания, но задания не выполняются, планировщик лог с ошибкой ниже:
[SQL: SELECT count(*) AS count_1
FROM task_instance
WHERE task_instance.pool = %(pool_1)s AND task_instance.state IN (%(state_1)s, %(state_2)s)]
[parameters: {'pool_1': 'default_pool', 'state_1': 'running', 'state_2': 'queued'}]

This probably means the server terminated abnormally
before or while processing the request.
The above exception was the direct cause of the following exception:

Если отключить statsd, все возобновится. Это ошибка для воздушного потока? любой совет, чтобы решить это?
