openmpi: 1.2.6
runtime: mpirun -mca mpi_yield_when_idle 1 (PBS -l nodes=32:ppn=8)
platform: intel dual quadcore, centos5
ib: Mellanox Technologies MT25208 InfiniHost III Ex

libraries from centos5:
libibverbs-1.1.1-6.el5_1.1
libibumad-1.0.5-6.el5_1.1
libibcommon-1.0.3-6.el5_1.1

I haven't had time to run this enough to know if it happens everytime or
only intermittently.
It takes a while before it happens...
