@LeandroDoldan and @alete89, would you mind providing a better description
of your config file ?
Are you guys using the official Airflow Helm Chart ?
The following DAG is a easy way to reproduce the error, would you mind
running it just to check if the bugs also disappear in this setting ?
```
from airflow import DAG
from airflow.operators.python import PythonOperator
import time
from datetime import datetime
dag = DAG('dag_test',
description='test',
schedule_interval=None,
start_date=datetime(2021, 4, 1),
max_active_runs=1,
concurrency=40,
catchup=False)
def my_sleeping_function(t):
time.sleep(t)
tasks = []
for i in range(400):
task = PythonOperator(task_id='sleep_for_' + str(i),
python_callable=my_sleeping_function,
op_kwargs={'t': 60},
dag=dag)
```
