High memory usage from UWSGI process

[ported-pw]

Environment

self-hosted (https://develop.sentry.dev/self-hosted/)

Version

22.10.0
OS: AlmaLinux 9, Docker 20.10.19

Steps to Reproduce

1. Install a fresh install
2. (import a backup) (probably not related)

Expected Result

System resource usage is reasonable

Actual Result

RAM usage of the UWSGI process (web?) immediately goes to ~50% of system RAM. After a while, the entire system also becomes unresponsive, hogging 100% CPU according to the hypervisor. This only seemed to happen due to side effects of going OOM due to the high memory usage, as it has been stable after increasing server RAM to 32GB.

[ported-pw]

We tested with increasing the VMs RAM to 32GB, and the UWSGI process shown in the screenshot is sitting at the same amount of RAM, pretty much exactly 8GB.

This seems not to be a web SDK problem. I just checked and it seems that @asottile-sentry made some changes to uwsgi stuff two months ago. Maybe he can help!

could you attach a memory profile via memray?

[ported-pw]

@asottile-sentry do you have any specific instructions on how I would go about doing this (since memray does not seem to attach live)? If not, could you tell me if I'm correct that this is web service?
Regardless, I should hopefully get to it tomorrow.

hello, is there any resolution? I'm also facing the same problem.

@SliverYuki can you attach a memory profiler and figure out why your instance has this problem?
