The message tells you everything:

 > forrtl: severe (179): Cannot allocate array - overflow on array size calculation.

For this calculation you may need a bigger computer (more RAM), or
use the mpi-parallel version (if you have a corresponding hardware) or

MOST LIKELY: make sure your cell is correctly defined (what are your RMTs, how many atoms ?)
              what is your RKmax ? Reduce it !
