RPi + ofx3DModelLoader : model disappears

I’m trying to use ofx3DModelLoader on the Raspberry Pi.
I’ve built the bundled example, it runs fine at 60FPS,
however after a couple hours the model disappears , but the scene keeps rendering (I can see the fps meter living normally on the corner).
Any thoughts ?
Tips for rendering 3d objects on the pi ?

Thanks in advance.

Hi Franz,
