ERROR in subspace rotation PSSYEVX: not enough eigenvalues found

Combines with PZSTEIN//PZNUMTR parameter number N had an illegal value and gam=****** trial= 1.911 step= NaN mean= 0.464. Custodian switches algo to normal, I'll try lowering timestep then switching to damped.

Overparallellization may also be a cause, try reducing nodes if you are parallellizing small cells.
