I’ve also encountered an apparent memory leak when uploading images.
In my case I’m deploying on Render using SQLite with uploads persisted to a disk. In the Strapi Media Library settings, I have ‘Responsive friendly upload” and “Size optimization” set to false.
I can upload 10 small images totaling about 324KB with no problem. But if I try uploading a batch of images that total about 25MB, the Strapi instance crashes.
(My project is on the starter plan with a 512MB memory limit.)
After crashing, Strapi will auto restart. When it does, it uses about 146M of memory. If I try uploading just one image at about 5MB, its memory usage jumps to about 290M. Even checking back on its metrics an hour later, its usage was holding at 290M.
I looked at the link bncngy provided. There wasn’t anything specifically for a Render deploy. I did try adding in a webpack.config.js file with configuration to exclude sharp, but it didn’t resolve the memory leak for my deployment. (I think bncngy was doing a Heroku deploy which has some additional options for resolving this.)
This sounds related to issue #14417.
Interested in any solutions or ideas anyone has for this issue.
