Well the most likely assumption is that there is some limit on the 
amount of memory you can use on that system, and you have made your block 
size so large that the total memory that FLASH needs exceeds the limit.

You are using on each MPI rank 136*136*136 cells (this includes guard 
cells). Multiply by number of variables times 8 (sizeof double precision),
and you the the number of bytes you need for solution storage (UNK) alone.
Maybe you just cannot use that much.

Not sure why this problem would only manifest itself in the first step of 
the evolution phase.
