I have a problem with ph.x.......when I try to calculate phonons at a 
q-point near Gamma, I get the following message:

     task #         8
     from set_irr : error #         0
     npert > max_irr_dim

And I also got it once at the Gamma point calculation of the phonons.
I'm using the latest version of the pw-scf code.

I have searched the pw-forum, but I haven't seen anyone else with this 

I thank you for your replies.
