DFTB+ keeps the eigenvectors for all k-points in the memory, so that its
memory consumption goes up linearly with the nr. of k-points. I'd
suggest to make separate calculations for small pieces of the k-lines.
Alternetively, you may use a parallel calculation with groups, where you
distribute the memory need over several nodes.
