This would well be caused by a version mismatch between your nodes.
E.g., if one node is running OMPI vx.y.z and another is running
va.b.c. We don't check for version mismatch in network
communications, and our wire protocols have changed between versions.
So if vx.y.z sends something that is not understood between va.b.c,
something like the above message could occur.
