Has anyone else had any problems with luxrender 1.0rc3? If I am just rendering a single image it works great.  But last night I started rendering an animation, reality 2.5 exported everything for lux, and the first two frames rendered great.  But half way through the 3rd frame, there was a sudden spike where I went from 14% mem usage to 100% mem usage and it froze.  I was rendering to a limit of 60 samples.  And I have 32G of ram.  So after I rebooted my computer, I restarted my the render from the third frame and put the rest in the queue, and it crashed again 3 frames later.
