I'm forwarding this to the OpenFabrics general list -- as it just
came up the other day, we know that Open MPI's UDAPL support works on
Solaris, but we have done little/no testing of it on OFED (I
personally know almost nothing about UDPAL).

Can the UDAPL OFED wizards shed any light on the error messages that
are listed below? In particular, these seem to be worrysome:

> setup_listener Permission denied
> setup_listener Address already in use
and
> create_qp Address already in use

Thanks...
