I'm trying to render fractals via an iterative method and it gets about 3%
in and complains of a stack overflow exception. What exactly is causing
this?

  Showing some (minimal) code can help solving the problem (or at least
finding it).

#macro M(A,N,D,L)plane{-z,-9pigment{mandel L*9translate N color_map{[0rgb x]
[1rgb 9]}scale<D,D*3D>*1e3}rotate y*A*8}#end M(-3<1.206434.28623>70,7)M(

You're using recursion that's going too "deep." If you're using functions
especially, you need to limit the recursion level. I'm not sure what the
limit is, but it's in the documentation somewhere.
