The zrd process may roll name.conf back which may cause unexpected changes. This shows up in the /var/log/gtm file or in the GUI with a message similar to the following: err zrd[27809]: 01150306:3: Error connecting to named socket 'Connection refused'. (or) err zrd[16198]: 01150306:3: Error connecting to named socket 'Connection timed out'.
Looking up or modifying zone records may fail. This will affect the other members in the gtm sync group as well.
As of now list include the following scenarios: -- One of the scenario is seen as part of ID1083405 - see https://cdn.f5.com/product/bugtracker/ID1083405.html -- Named process isn’t running, updating wide IPs will cause the same symptom.
