I imported this cloud tgc file called Tornado. As soon as I started rendering, I got all these TraceRay & Bucket Render Errors.
From what I read, this is usually a problem with low ram. My system is as follows, windows 7 64 bit, 24 Gigs of ram, Processor is 6 core I7 980X, video card is a Nvidia 4000 PNY Quadro Fx.
The settings in preview render were not high at all. Task manager was showing utilization of only 18% of my physical ram.
What causes these errors?
