I'm quite happy with C5Pro, but I've been getting memory allocation errors lately when rendering scenes with volumetric clouds (haven't used many). I watch Windows Task Manager to see if memory requirements are the problem, but this is not the case.

The problem seems to be occuring when also using surface distribution with imported objects.

This is occuring on my 3.6 GHz Dell 370 workstation with 4 GByte of RAM, and an NVIDIA 6800 card with 256 MByte of VRAM. This box is very stable, and I can run up to ~1.85 GByte during a render before the system becomes unstable.

I have the 5.0.2 patch.

This is being reported.
