SIGKILL ERROR in Flask app

1

Hi, I’m building an AI app using flask. My backend takes sometime to process the request. However, after 45-60seconds, I’m getting this error:
Oct 24 02:56:13 PM [2023-10-24 13:56:13 +0000] [52] [CRITICAL] WORKER TIMEOUT (pid:89)
Oct 24 02:56:14 PM [2023-10-24 13:56:14 +0000] [52] [ERROR] Worker (pid:89) was sent SIGKILL! Perhaps out of memory?
Oct 24 02:56:14 PM [2023-10-24 13:56:14 +0000] [98] [INFO] Booting worker with pid: 98

I’m currently on the free plan, to test this application. Please let me know how to resolve this issue.

Hello there…
Try gunicorn --worker-class=gevent --worker-connections=1000 --workers=3 app:app instead of gunicorn:app
