fatal : Memory allocation failure

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

IT JUST USES TO WORK EASILY.

### Actual Behavior

Got this error and silent crash when the vae decode is working, with 128GB ram and 96GB vram. Have no idea why? How much ram does it need?

And some time it even makes PC black screen (so 128gb is not enough for decoding?). I don't understand what your memory strategy is doing actually.

### Steps to Reproduce

Using lastest commit, run a flux2 workflow

### Debug Logs
