Hello,
I am making a phonon test calculation  and I set the parameter
maxirr=5, just to investigate the convergence of the accustic modes with
the cutoffs. Calculating all the modes takes too much time.
However, the code does not stop in the fifth mode, and
continues calculating the higher modes. Was is wrong with my input file?
