Hi,

here we go:

##################################

global_settings {assumed_gamma 1.5  max_trace_level 5}
#declare rnd1=seed(1);

#declare n=900;
#declare r1=1;
#declare r2=5;

#declare k=1; #while(k<=n)
    #declare P=<rand(rnd1)-0.5,rand(rnd1)-0.5,0>*r2;
    sphere{<0,0,0>,r1 pigment{rgbt 1} hollow no_shadow interior{media{emission
1/r1}} translate P}
#declare k=k+1; #end

camera{location<0,0,-5*r2> look_at<0,0,0>}

##################################

As you see, n is the number of spheres, r1 their radius, and r2 the edge length
of the box which contains all spheres.

If I set r2 = 2 the error occurs, but for r2 = 5 (and otherwise same values)
rendering works.

Maybe this helps?
