asterisk users - Dec 2017 - Asterisk 13.18.4 - New Error PJLIB_UTIL_EDNS_REFUSED

We just updated from 13.17.1 to 13.18.4 and are noticing a new error
  
 [2017-12-21 10:12:48] ERROR[32343]: res_pjsip.c:3850 endpt_send_request: 
Error 320055 'DNS "Refused" (PJLIB_UTIL_EDNS_REFUSED)' sending
OPTIONS
request to endpoint 6162480909.8009
 
 The DNS on the system seems to be working find. Anyone have an idea what 
could be triggering this issue?

Thanks

I don't see anything offhand between 13.17.1 and 13.18.4 that would cause
these.  How often are they happening?
