Are you sure the relay is not being "hot switched" ?
I use RJ1 relays in two of my amps, with RG-142B/U connected
directly to the relay terminals. Both amps have many hours with no
relay failures and both have been run QSK much of the time (so a lot
of switching). The coax has some rather sharp bends near the relays,
so it does exert some physical stress on the relays.
