   I had something similar on the SP2 when the MPI
implementation was unable to allocate memory for internal
purpose in some routines (such as MPI_BARRIER). There does
not seem to be any user control on this so the only solution
I could find was to try to reduce arbitrarily memory usage
at the application level.

   I would also be interested if someone knows more on this.
