| ADVICE TO THIS USER RUNNING 'VASP/VAMP' (HEAR YOUR MASTER'S VOICE ...): |
| |
| You have a (more or less) 'large supercell' and for larger cells |
| it might be more efficient to use real space projection operators |
| So try LREAL=.TRUE. in the INCAR file. |
| Mind: If you want to do an extremely accurate calculations keep the |
| reciprocal projection scheme (i.e. LREAL=.FALSE.) |

Probably your memory is not large enough. Adjust the input parameters which
influcence the memory size (PREC, nr. of k-points,..)
