When you change major RHEL release # and OFED version #, it's a pretty safe bet
that you would need to rebuild Open MPI.

P.S. There was no Open Fabrics OFED 2.4 (Release #s jumped from 1.5 to 3.5)
, so I guess this is a Mellanox OFED 2.4.
From: users [mailto:users-boun...@open-mpi.org]
On RHEL 5 hosts which have OFED 1.5 installed, we have builds of OpenMPI 1.4.5
and 1.6.5 in place.
On RHEL 6 hosts we have OFED 2.4 installed. Will we need to rebuild OpenMPI
1.4.5 and 1.6.5, or can our existing builds of such still work on the RHEL 6
hosts?

Alexander,
i was able to reproduce this behaviour.
basically, bad things happen when the garbage collector is invoked ...
i was even able to reproduce some crashes (but that happen at random
stages) very early in the code
by manually inserting calls to the garbage collector (e.g. System.gc();)
