Try providing source/destination addresses.  E.g.

fi_rdm -p tcp -s

fi_rdm -p tcp

Also, fabtests are not maintained to be backwards compatible, so make sure you're using fabtests built against the libfabric version that you're using.

I did find an issue in rxm related to tcp which could be impacting you.  (I'm skeptical because other's would have noticed this before).  That fix is in the upstream master branch.
