It's probably a bug in MPE, unfortunately.  I don't think we have funding to work on MPE right now, though we would welcome patches if someone wants to dive in and fix the issue.

I've filed a ticket so that the issue isn't totally lost: https://trac.mpich.org/projects/mpich/ticket/1794

Thanks for letting us know,
