This is not an Amber error message: it comes from your MPI implementation.
It has nothing to do with how you built your topology files, and so on.
Can you run the parallel test cases? If not, that is the place to start,
and you may have to consult your MPI documentation (what MPI are you using?)
If you can run the parallel test cases, look carefully to see if there is
anything different in the way you are running those, and the way you are
running this job (the one that fails).
Others on the list may recognize the exact error message, and be able to
suggest a specific fix....
