To me, this likely indicates your RDMA setup is broken. Do commands like ibstatus and ibv_devices report active interfaces? Do other RDMA test programs like ib_write_bw, etc (from the perftest package) work? It may be worth printing the errno with that error message, I may have time to make a patch to that effect tomorrow.
