this seems an app issue, I'd probably try to just redeploy, do you save stuff in a memory cache?

my app is very simple, it's just api connecting to postgresql and r2 cloudflare to store images, ram was still low before, my latest deploy on 31st, RAM spiked at 22:00 time zone +7 on 02/11/2025, but at that time it seems the number of users was very low, it can't spike like that. I don't know what the problem is.

how do you upload the files? directly in R2 or do you upload in your app and then R2?

if you upload trough the app, can it be that someone uploaded a very big file?

there seems to be a spike in the network as well when you had the spike in memory, maybe they are related

This is my api upload file, can you please review it for me? my limit is 20mb, if there is a sudden change at a certain time, why does it last from 22:00 to now? is it not released and stuck? Thank you.

can you try to redeploy the service? hopefully that's should reduce the memory, then you should just debug your app, add logs, check memory consumption and do some load test locally

Thanks, I have restarted the service and am monitoring further for any action.
