Error in routine read_ephmat

Dear all
I encountered the following error while using EPW v.5.4 to calculate the anisotropic superconducting gap.
I'm using PAW pseudopotentials and my input files are also added below.Although I tried my best to read the source code, I still don't understand why this error occurs. Any help would be greatly appreciated !

Dear qdhao:

You are encountering the issue with large memory footprint and you need to check my previous post at viewtopic.php?p=4497#p4497 .

Well, this is not related to your issue, but I would suggest you to use norm-conserving pseudopotentials.
Rigorously speaking, both PAW and USPP have issue with the symmetry relation of electron-phonon vertex.

Sincerely,

H. Lee
