[Pw_forum] Problems computing cholesky

[Carlo Motta]

Dear all,

I am facing a problem with the widely discussed error  "problems computing cholesky".
I searched in the mailing list archive, but I couldn't find a solution to my problem. 
After successfully running an "scf" calculation, I run a "bands" calculation which gives this error while computing the kpoints:

     Computing kpt #:     1

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine  cdiaghg (245):
      problems computing cholesky
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

This problem arises with both 5.0 and 5.1 versions. Doing some tests, I found that if I decrease ecut and kpoints to ridiculously small values, the error doesn't show up.

Any advice is welcome!

Kind regards,
