I was doing some calculations on a slab model to find out the proper thickness for the slab. When I increases the number of atoms from 60 to 68, VASP gave me this error then exited.
I have made it sure with "diff" command that all other files (INCAR, KPOINTS, POTCAR) are unchanged. I only made the z-vector longer and added 8 more atoms.
Could anyone tell me how to fix this problem? Thanks.

please change the parameter NMAXM in the fftw3d you use to the suggested value and re-compile vasp
