Darby,

We have tested with 6GB per background process, but we haven't done
significant testing above that.

The likely worst thing that happens is that you're wasting RAM because<= br> the rendering process doesn't need what you're feeding it, so you&#= 39;re
unnecessarily taking away from such things as the RAM cache and the OS
and other applications.
