Ever since I upgraded to Cactus 4.2.3, my code seems to have issues with MPI and PUGH.  For example, when I perform an 8 processor run, I get 8 copies of full grid output instead of the 8 processors splitting up the grid and creating 1 output.  This works with both the arrangements I wrote and WaveToy.  Any ideas how to fix this?
