What about using:
Hi All,
using ompi 1.4.5 or 1.6.5 for that matter, I came across an
interesting thing
when an MPI function is called from in a recusivly called subroutine
(Fortran Interface)
the MPI_ALLREDUCE function allocates memory in the OMPI_LIST_GROW functions.
It does this indefinitly. In our case OMPI
This is not supposed to happen. Can you please post an example highlighting
this behavior?

I will post a small example for testing.
It is interesting to note though that this happens only
when MPI_ALLREDUCE is called in a recursive kind of way.
Is there a possibility to limit the OMPI_free_list groth, via an --mca
parameter ?

Yes, the number of elements each freelist accepts to allocate can be bounded.
However, we need to know which freelist we should act upon.
What exactly you means by "MPI_ALLREDUCE is called in a recursive way"? You
mean inside a loop right?
