Anyone seen this message on rad-generated rpiece runs lately? I just saw on one of the eight-core systems on our big cluster and I'm wondering if anyone else has seen it.
I'm running the CVS version of Radiance, so it could be that I just built on a bad day.

Hi Randolph,
This shouldn't happen, unless one of the rpict processes died unexpectedly. Even then, I would expect some other kind of error to be reported as well.

Thanks, Greg. I think that's what happenned; in fact seven of the eight died in two cases. Wierdly, the third succeeded. If I run it as a single-processor job, it works. Here's a piece of the log:
