This error indicates an error while reading in the POTCAR. It can, for example, occur when using the new POTCAR format with the old version of VASP, or vice versa.
An obscure Chinese site also suggests that this might occur for unreasonable geometries, e.g. after too large steps in the ionic relaxation.
