I'd hazard a guess that you had a cambium radio decided to get sync-over-power where it only has timing sync, or vice versa. We've seen that happen since the new auto-sync system came in.

It is re-registering like crazy, like every 30 seconds or so. The spectrum is clean (the portion it is running in), RX is -68 on both ends. The really odd part is this: If you watch the S/NR on the slave, the H pol will start around 23db, slowly climb to 30 then the radio will dump and re-register. The V pol stays constant at 25dB S/NR. I have not tried newer firmware. The link is running 12.something (I think). Any ideas?
