[Pw_forum] problems computing cholesky

[Kanak Datta]

Dear researchers

I have been trying to perform bands calculation in pw.x for monolayer MoS2.
I have done scf calculation using Norm Conserving PBE functionals. However,
while doing bands calculation I get the following error:
     Error in routine  cdiaghg (1696):
      problems computing cholesky

I have seen that if I reduce the number of bands in the bands calculation,
the error does not appear. However, I need to simulate bands with a large
number of bands. Can anyone suggest a possible way around this problem?

Thanks
Kanak
