Bug [2021.2.15b] Initial import floods 32GB RAM and crashes OOM

I'm trying to import our existing project (Aprox. 50GB library folder in size) into the latest Unity beta and on a fresh import from deleting the library folder, Unity will fail to import on the first launch as it eventually eats up all 32GB of memory on my dev PC.

I enjoy all the improvements to the import pipeline for sure, but I feel like it may have become a bit too agressive and needs to scale itself based on available memory.

 

Try with a project that does not include the library folder to see if it still happens.

 

I did do this yes.

 

This happens for all all the time, when the Editor tries to import the SpriteAtlases and PSB files. I would recommend to check for those and maybe disable disable the sprite atlases in Editor.

 

The one with the Sprite Atlases is hard to reproduce, but I made a new bug report for the PSB files: Case 1372221
