What version of Wien2k are you using, particularly the mixer (grep
MULTISECANT *.scfm)?

Your calculations are "starving to death". The step size is so small (both
the GREED and Beta) that it is bouncing around on numerical noise. It may
well have already converged to the limits of the noise/conditioning in your
calculation, which is linked to RKMAX and the k-mesh and also (Peter's
response) from TETRA. The iterative diagonalizations also introduce some
noise.

For the specific case I would remove the prior history (rm *.broyd*) and
continue it.
