             Summary: RpcMgrTest.SlowCallback and RpcMgrTest.AsyncCall sometimes have port conflicts
                 Key: IMPALA-8501

Failed to add acceptor pool: Network error: error binding socket to 127.0.0.1:55500: Address already in use (error 98)

This is running on centos 7.

It looks like the ephemeral port is searched-for during the startup of the test binary and only used later, so these tests have a bigger race window than others. It would be good to defer finding the ephemeral port until it is about to be used.
