This is actually a common problem for test fixtures that involve miniature coaxial connectors (pretty much all of them are rated for few tens of mating cycles): even if the connector on device is used for assembly/repairs and goes through very few mating cycles, the automated test fixture used during manufacture of such a device is expected to last longer.
Most connector vendors have specialized connectors for test fixtures that last much longer (they are also a lot more expensive).
