Dear All,

When doing ECP spin-orbit calculation I've got the following message:

>   unexpected off diagonal block element in SO matrix.
>   The following matrix element is greater than the threshold of 10d-12:
>   row    = ibra =   6 ivsym(ibra) =  2  stls(ibra) =  1.1
>   column = iket =   5 ivsym(iket) =  1  stls(iket) =  1.1

How does it affect the results of spin orbit calculation - are they
meaningful in that case? What might be possible reasons of such
problems and how generally avoid them?
