Dear Hongjun,
You should raise nstep, as the code suggests. The error message is telling you that you are doing too few self-consistent cycles.

Dear users of ABINIT:
When I calculate Wurzite InN ,I have some trouble in SCF cycles.


It is also the case that InN in GGA or LDA has
a very small or zero gap, in which case dealing with
it the metallic way may be a good idea (smearing
and such).

Vincenzo
