It might or might not, depending on your settings, scene and your memory 
limits.

You have two options:

- use more reasonable radiosity settings (if the render takes more than 
8 hours with just a patch of grass they most likely are not).
- make more memory available to POV-Ray (by changing your OS settings or 
getting a computer system with larger address space).
