The recommended fix for this is to use the Hydra process manager with MPICH.
Hydra ships with MPICH since version 1.2.
See this MPICH FAQ entry:
http://wiki.mpich.org/mpich/index.php/Frequently_Asked_Questions#Q:_I_don.27t_like_.3CWHATEVER.3E_about_mpd.2C_or_I.27m_having_a_problem_with_mpdboot.2C_can_you_fix_it.3F
Or you can also use Open-MPI which work out of the box.
