I am running microblog.pub + Caddy based reverse proxy on virtual server with 1GB RAM. But if I upload image, e.g. full size 3744x5616 image from https://www.pexels.com/photo/selective-focus-photo-of-pile-of-assorted-title-books-1148399/ then I see

2023-01-22 14:34:27,014 INFO success: uvicorn entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)
2023-01-22 14:35:35,421 INFO exited: uvicorn (terminated by SIGKILL; not expected)
2023-01-22 14:35:36,157 INFO spawned: 'uvicorn' with pid 25913
2023-01-22 14:35:37,159 INFO success: uvicorn entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)

No problem with smaller images, e.g. 1920x1080, or videos.

Possible solutions

• use different library or way to strip EXIF metadata
• resize image and strip EXIF metadata
• reject upload when size is bigger than ... and image has metadata
• ...
