That is the infamous 'stuck beacon' issue... Essentially, every time you see that in the log of an AP, for about couple of seconds that AP totally stops communications (TX & RX) while doing a reset. This is a bug associated with the atheros chip set used in the Rocket M.. XW firmware designated ones are with a different chip set...
This problem shows up in moderate to heavy RF interference environments. For IP Services, even video (due to buffering) the effect is minimal, however for voice services the affect is bit more disastrous (causes very distinct voice drop outs). Radios using GPS sync can avoid such issues. FWIW:- Radios not using GPS sync are supposed to have a full 20mhz channel separation between adjacent Radios (AP)...... EPMP Radios (AP) with GPS Sync only need 10mhz channel separation and PMP needs only 5mhz channel separation. Say in your environment, you are most likely causing your own noise and interference (assuming that there is no other provider) with the non gps sync radios, and there is a very good chance that you are not getting the most out of your Fixed Wireless Network (the current performance may very well be acceptable, but not the most efficient). If you were running GPS sync radios, then your channel use would be much less (due to channel reuse), and you would be not creating your own noise, and as such having a more efficient Fixed Wireless Radio. GPS is not a magic bullet, but it is a very powerful tool in keeping things running well and using limited resources very efficiently. It is purely my opinion that in 802.11ac, because getting larger amount of thru put requires fat channels (40/80/160mhz), it is even more important to have GPS sync, so that you can have a function, effective channel reuse.
