Steve, I thought you said earlier in the thread that the rdmacm OMPI
method is not used that often with IB - and the other IB connect
methods work fine.

This really is a bug in OMPI, how long do you think this new feature
should remain outside the upstream kernel? Is someone going to commit
to fixing OMPI soon if the patch is removed?
