[Pw_forum] from cdiaghg : error # 2012 diagonalization (ZHEGV*) failed

[pmoreira at ifi.unicamp.br]

 I tried to run QE but the followinhg error is happening:

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #         0
     from  : error #      2012
     diagonalization (ZHEGV*) failed
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

 My input follows below. The atomic positions were cut, because they are
long and were checked with XCrysDen. I am trying to model an apatite.I
did some tests suggested on user manual (cdiaghg error), but I cannot
figure out where my problem is, but I think it is with the
pseudo-potentials. If someone could a point some direction, I would be
grateful,

 With best regards,
