Do you freeze all your octrees?
Scene data in the tens of MB are common, but a non-frozen
octree beyond 10 MB should be rare.

There are no inherent limits, if you answer the right questions
when compiling (or at least I'm sure you haven't run into *those*
limits yet).

I finally found the avlmemi error in some old mail:
Your problem most likely has to do with a defective qsort()
routine in Linux. Radiance uses this routine in the context
of an attempt at saving some memory when the ambient data
grows beyond a certain margin. If you have lots of RAM, then
you don't really need this, and you can set the margin to
a very big size with the following compilation option:

 -DSORT_THRESH=0x7fffffffffffffff


Have fun!
