Sorry! It means you've hit the resource limits of your Streamlit Cloud account. One way to avoid this is to upgrade your plan to one with higher resource limits. But there are also a few things you can change in your app to make it less resource-hungry:
Reboot your app (temporary fix)
Use st.cache to load models or data only once
Restrict the cache size with ttl or max_entries
Move big datasets to a database
Profile your app's memory usage
