atom ID set to zero

Hi Lammps Users:

I want to know under what circumstance will an atom’s ID being set to zero, during a MD run. In my data file all atom ID’s are valid, meaning they are positive integers. However, when I check the dump file later at a certain time step, I see one of the atoms had a zero ID. Is it a but or I have something going wrong with my model? Thanks.
