There is a bug in the MPICH registration code and there is a patch available. You can download the patch, clearmpichkeys, by going to this web page, <a target=_blank href=""></a> , and choose the link, "MPICH Patch".

This patch will clear the MPICH registration keys and removes the user's MPICH cryptographic context that holds the cryptographic keys. Then new keys can be generated.

Instructions for applying the patch can be found in the link above.
