Too many atom sorting bins

AIREBO is a combination of REBO and LJ with a switching function to switch
on/off the LJ part. I wonder why you use a hybrid of airebo and lj/cut in
your script - it does not seem right. Have you tried just use pair_style
airebo and still get the same error?

I changed it because befiore i had nsq and i was getting the error of ?Too
many atom sorting bins ? ,and lammps manual was suggesting to change it to
bin.i minimize my system first and then i start my simulation?it have the
same error of ?Too many atom sorting bins ? .
