[gmx-users] MPI issue

I am running gromacs on a machine with altivec support. My understanding is
I have to use MVAPICH on this machine.
I occasionally have runs crash and I receive the following error
n559(0): Loaded with Money
n536(14): 14 - MPI_ALLREDUCE : Null communicator
n536(14):   Aborting Program!
n559(0): 0 - MPI_ALLREDUCE : Null communicator
n559(0):   Aborting Program!
Cleaning up all processes ...Cleaning up all processes ...done.
Does this indicate a problem with the machine, mvapich, or gromacs? Again,
this doesn't always happen, just sometimes (which makes me suspect it is a
machine issue). Any advice on where the problem might be would be helpful.
thanks in advance.
