2 times out of 338 transfer (attempts). Probably, when there is
traffic the port can't be bound immediately even if it was
released very short ago by the previous process.
This test could not reproduce the problem (when reusing immediately
the same port number for the next request), so FDTD.getFreePort()
was reimplemented to reserver ports on round-robin basis.
