   Seeing this on 1.10.8 with Celery executor.
   We are running the scheduler with num duration 900 seconds. It would run fine for a couple of days then suddenly just freeze.
   
   ```
   Thread 1 (idle): "MainThread"
       wait (threading.py:295)
       wait (threading.py:551)
       wait (multiprocessing/pool.py:635)
