I don't think so. Some of these render boxes have 4 GB of RAM with 180 GB drives that are virtually empty.

The bizarre thing is that my scene has 10 different files that make all of the different render passes and the heaviest one of them is the one that almost NEVER fails.

The good news is that Mental Ray on the farm seems rock solid so after this project I'm just going to render with Mental Ray as often as possible.
