Vashishta and reax/c potential

There could be issues with the model, ReaxFF, your LAMMPS input deck, …etc.

Did you get error during annealing simulation with reaxFF?

yeah, a frequent oversight is to forget having to change units. ReaxFF
parameter files require "real" units, not "metal".
that has implications on time step, velocities etc.
