i think i've found the problem: as long as `Variable` is used. `lsof`
results (`type=STREAM (CONNECTED)`) keep growing:
```python
"""Test"""
# airflow DAG
from airflow.models import Variable
from airflow.models.dag import DAG
from airflow.operators.empty import EmptyOperator
from airflow.timetables.trigger import CronTriggerTimetable
from pendulum import datetime
LOCAL_TZ = "UTC"
accounts = Variable.get(
"dummy_accounts",
default_var=["dummy"],
deserialize_json=True,
)
with DAG(
dag_id="dummy_daily",
schedule=CronTriggerTimetable("@daily", timezone=LOCAL_TZ),
start_date=datetime(2025, 5, 1, tz=LOCAL_TZ),
max_active_runs=3,
catchup=False,
tags=["flag"],
):
for account in accounts:
step_1 = EmptyOperator(task_id=f"{account}_step_1")
step_2 = EmptyOperator(task_id=f"{account}_step_2")
step_1 >> step_2
```
replace the `Variable` with `accounts = ["dummy", "drummer"]`, everything is
hunky-dory
