I'm running Carrara 6 Pro on a MacPro, running Leopard. 

I'm attempting to render an HDRI render - fairly low resolution: 640x480, 72ppi, nothing fancy. The render gets about halfway through and then Carrara crashes. The scene really isn't complex - one model, a floor and two walls. I've got three Anything Glows lights in place, to replicate flourescent lights. 

What can I do to alleviate this problem? Thanks in advance!
