[Pw_forum] phonon segmentation fault

[Eduardo Ariel Menendez P]

Hello,
I m trynig to do a phonon calculation with ph.x version 3.1. The code
aborts like this
**********************************
     Representation   124      2 modes - To be done

     Representation   125      2 modes - To be done
     PHONON       :    15h13m CPU time

/home/eduardo/opt/mpich/1.2.7/bin/mpirun.ch_p4: line 243: 14349
Segmentation fault
"/home/eduardo/Compilaciones/Espresso/3.1/bin/ph.x" -p4pg
"/home/eduardo/MyPWSCF/CdTe/Defect/PI14169" -p4wd
"/home/eduardo/MyPWSCF/CdTe/Defect"

The example 02 seems to work ok.

Should I find the cause in MPICH compilation or in Espresso?
The system has 63 atoms? Is it too big for ph.x? Memory limited?

Thanks
Eduardo
