Dear cp2k users,
when I tried to run a periodic HF calculation or a mixed HF-DFT run 
(b3lyp). I got following error. Could anyone please help to understand this 

 HFX_MEM_INFO| Est. max. program size before HFX [MB's]:                   

 *** 13:32:08 WARNING in hfx_energy_potential:integrate_four_center :: The 
 *** Kohn Sham matrix is not 100% occupied. This may result in uncorrect   
 *** Hartree-Fock results. Try to decrease EPS_PGF_ORB and                 
 *** EPS_FILTER_MATRIX in the QS section.
