Comment (by Roland Haas):

This was discussed in today’s ET call. While difficult to diagnose remotely, the suggestion were that this may be due to mismatched MPI stacks during compile and runtime or due to incorrect LD_LIBRARY_PATH. Without access to the system though, this is almost impossible to correctly diagnose.
