Reduce your cell resolution (make cells larger).  I'm surprised you're 
running out of memory.  Cell resolution can have a big impact on this
for pretty much all raster/imagery modules.

Those 2.4.x kernels are known to have some memory management issues.
Reportedly, 2.4.10 is working better for some people...
