I just ran a test on my system, and the -c option worked okay.  Looking at your configuration, I don't see anything standing out as an issue.  If you run rdma_cmatose without any options, does that fail for you as well?  Can you also try adding -p port_number to the command line?  Maybe there's a port collision for some reason.
