ERROR in running LIGGGHTS

Hi all,

I am trying to run a LIGGGHTS code on a PC. The compiler is able to almost go through all the steps except the last dump and run commands. I am encountering below error. Can anybody explain what's the exact problem ? I tried searching in forum, but haven't found my luck.

Thanks in advance.

ERROR on proc 0: assertion failed (../region_neighbor_list_I.h:161)
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
