Getting help to solve the error for "Bond atoms 5282 5291 missing on proc 0 at step 2515 (src/ntopo_bond_all.cpp:61)"

Hi there!

I am running a system of L-serine substrate, using CHARMM force field. During the process of NPT and getting the final results, I have faced the following error:
“ERROR on proc 0: Bond atoms 5282 5291 missing on proc 0 at step 2515 (src/ntopo_bond_all.cpp:61)
Last command: run 2000000”

Could anyone please help me to resolve this issue?
In case it is needed, I have attached my error script here.

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

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.

This typically means your simulation had bad dynamics. This could be due to incorrect force field parameters, too large a timestep, etc. One thing that stands out is you had 23 “dangerous” neighborlist builds, which means that you need to increase the neighbor “skin” distance or decrease the timestep.
