did you try to increase concurrent DAG runs and task executions If limits
are too low, the child_dag may get stuck in the queued state.
In your DAG definition, set higher limits:
```python
Copy
Edit
with DAG(
dag_id="child_dag_id",
max_active_runs=3, # Increase if needed
concurrency=16, # Controls how many tasks can run in parallel
...
) as dag:
```
In airflow.cfg, check and increase the following parameters:
```
parallelism = 32 # Total number of task instances that can run
in parallel
dag_concurrency = 16 # Tasks per DAG that can run at once
max_active_runs_per_dag = 16 # DAG runs per DAG allowed at the same time
```
