@yuqian90 I have almost the exact same environment as you, and I have the same problem. - Airflow 2.0.2 - CeleryExecutor (postgres result backend, and redis broker) - Single scheduler - Python version 3.8.5 The problem happens roughly twice per day. I get the same last log message you do: `Exiting gracefully upon receiving signal 15` and the exact same py-spy output. As a last resort, I plan to watch for a hanged subprocess of the scheduler and kill it in a cron job... just like you, when I kill the subprocess manually, the main scheduler process continues as if nothing happened. -- This is an automated message from the Apache Git Service.
