Dear Pwscf users

I have a problem in using average.x,
after DFT ground state calculations i use pp.x for saving  the V_bare + V_H
potential in  "fermipot.dat" file.
I want to use average.x for average the data saved in the file for obtaining
the fermi level(follow the instruction of work_FCT example of espresso)
i use the following input file for average.in:


where if i am not wrong,*55.809 is my lattice constant in bohr and i want to
get 500 data finally.
but the program average.x is steel running after two  days for a 16
processor server and in .out file i see:

Reading header from file  fermirefpot.dat

the cpu is fully engaged but the memory usage is 0%!
i think there is something wrong in my input file.*I try to change some
parameters like "3->2 or 1"  and "500->1000 or 300" but the result is the

i would be really grateful *if you could help me,
Thanks indeed for your time and kindness
