Deployed app crashes once in a while with no obvious error logs

My streamlit app just crashes once in a while with no other logs except for:

Streamlit server consistently failed status checks
Please fix the errors, push an update to the git repo, or reboot the app.

Then I would reboot again, and it will come back up. What would be causing this issue? Link to the app

Have you profiled your app’s resources? There is a 1GB resource limit for apps deployed in Streamlit Cloud. Both disk space and memory are relevant. Use of caching can increase resource use over time, as well.
