Description
Every 5-10 minutes, cursor will crash because the window[num](filename - repo name) exceed 5GB of memory usage. (this is the sole process that eats up the memory)

I confirmed that it is not because of extensions after disabling.
I’ve also added pretty exhaustive ignore rules in pyproject.toml and settings.json

Stack information

  • using uv and poetry for dependency management

Version 0.45.11 has some performance improvements that should help with the memory issues you’re seeing. Try updating to that version first and let me know if you’re still seeing the crashes

Thanks Dan. I’ve been on 0.45.11 for the past week but the issue persists. Someone else on the forums commented there’s a loose relationship with the composer chat length - which has been my experience too just fyi

Got it - yeah this is a known issue with longer chats. Try starting fresh composers more frequently to keep things running smoothly. The team is working on improving performance, but for now that should help reduce the crashes you’re seeing
