After several months of code stability I experience now the famous 
infamous dependence of my results on the # of CPUs (and more precisely, 
divergence with -np > 4). I upgraded Petsc version meanwhile, but I want 
to start by assuming I have a problem. Any pointers to how to set up a 
trap for this bug are highly appreciated.
