Confirmed in 1.18.2. Not random for me in short term. But inconsistent in different time. Code review find out SRV processing just ignore priority. For SRV record, only take port and address for the first item in records list. Records list is an unsorted list and not even ensuring the highest priority record in the first item. Code is similar to the code posted in privious comment.
