Not being an expert on Big Ben, I nevertheless wager a guess.  A  
segmentation fault can be caused either by an error in your code, or  
by your simulation running out of memory.  Try to estimate how much  
memory you need on every processor, and compare that to the available  
memory on each node.  It may be necessary to use more processors in  
order to reduce the per-processor memory requirement.

If you use PUGH, then the option PUGH::storage_verbose = yes can help  
you.  If you use Carpet, then the option  
CarpetLib::print_memstats_every = 1 may help.
