Hi BIND Users, In one of our customer sites, the DNS process was found running on multiple cache serversbut is was not responding to a dig @localhost.
The named version is BIND 9.5.1-P2 with security fixes from BIND 9.5.2-P3. The named process was in a hung state. The recursive cache could not communicate with the roots. Therefore the queries were timing out causing a wide spread outage. Restarting the DNS process resolved the problem. The servers had an uptime of over 300 days. There are no significant lines in the /var/adm/messages or in named.log to pinpoint the problem. Could this version have anything to do with the recent BIND bug that was fixed via BIND 9.7.3-P3? Did our customer hit a known bug? Any help regarding this will be appreciated. general: info: sockmgt 1006e49b0: maximum number of FD events (64) received lines are seen in the logs. Thanks Sam. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
