It seems that mt-framework lacks process synchronization because fork() cannot determine the execution order of (parent & child) processes. We need to finish rdma_listen() in child before running rdma_connect in parent by some mechanisms (e.g. futex, semaphore, signal? not sure which one is the best).
You are right @yangx-jy. I think the easier way is to provide an interprocess-synchronization based on semaphores. I have proposed a very rough proof of concept. But it requires some additional work to become an elegant solution.
As for now, I recommend turning off all tests that have sneaked into our CI introducing this issue.

Maybe a synchro issue in the MT-framework?
