[QE-users] error in postprocessing with dos.x and projwfc.x QE 7.4.1

[giuseppe.mattioli at mlib.ism.cnr.it]

Dear users and developers
I've completed, apparently with no error, a huge calculation with QE 
7.4.1. exiting with proper message

      PWSCF        :  20d15h10m CPU  22d 8h42m WALL


    This run was terminated on:   6:47: 8  22Dec2025

=------------------------------------------------------------------------------=
    JOB DONE.
=------------------------------------------------------------------------------=

Now I want to postprocess the results, as I've done thousands of times, 
using dos.x and projwfc.x. I've not tried with pp.x, yet.
However, dos.x and projwfc.x stop and complain:

This is dos.x

and this is the analogous behavior of projwfc.x

What can I do? I'm a bit nervous because the main calculation ran for 22 
days...
Thank you in advance for your attention and for hints and tips
