flask apscheduler start once but run many times

I use 

from gevent import monkey
monkey.patch_all()

and use apscheduler.BackgroundScheduler()
use gunicorn run flask:

gunicorn -w 4 -b 0.0.0.0:9999 -k gevent main:app --preload

the cronjob start in main.py, it start once, but run 4 times. if I not use monkey.patch_all(), it run once. Why and how can I use monkey patch and run cronjob once.

I use sse(server-send-event), so I have to use gevent and the monkey patch.

You should try to up (or install) watchdog on your environement.

Personally i don't use monkey, you can try from gevent :

from gevent.pywsgi import WSGIServer

if __name__ == "__main__": http_server = WSGIServer(("0.0.0.0", 5001), app).serve_forever()
