crash on particle rendering

I’ve got a pflow disk cache with 800,000 particles and I’m using the Shape Instance modifier as a post-cache operator. It works great in the viewport but vray can’t seem to render it. I get this error:

Seems to happen regardless of what “Geometry” render typ I use (Single mesh, Multiple meshes, mesh per particle).

Hello,

Can you send us the scene for further investigation?
