NAMED issue

[Sudharanjan Patnaik]

Hi Team,
We are facing an issue with BIND since last 1 year, will you be able to help.
We have a DNS master and 4 Replicas at 2 sites.
Current BIND version: 9.9.9.P5 (recently patched to P5).
Issue: The named process is getting hung or stopped at least once a day on each of these Replicas. This is happening since more than 1 year. Meanwhile, many vulnerability patch versions upgraded and currently running with the latest BIND 9.9.9.P5.
Temporary Fix: A script is running to check and restart the named process if stopped or hung.
OS Version: AIX 6.1, TL 9

Though our DNS master is also running with the same version, we never faced this issue.
Please Note: all the DNS queries goes to the Replicas and none to the master.

Thanks and Regards.

Sudharanjan Patnaik
