| 2023-10-20 11:29:18 | Marian Gasparovic | description | MAAS 3.3.5 We noticed in test runs that our staticaly defined VIP addresses for openstack services sometimes don't resolve and a minute later they are fine. Turns out bind servers restarts often, tens of times a day. ``` $ grep "starting BIND" named.log*|awk '{print $1}'|sed "s/.*://"|sort|uniq -c 15 12-Oct-2023 67 13-Oct-2023 175 14-Oct-2023 170 15-Oct-2023 34 16-Oct-2023 41 17-Oct-2023 36 18-Oct-2023 73 19-Oct-2023 15 20-Oct-2023 ``` Christian had a look and he found that BIND is getting restarted frequently because MAAS checks the serial for each zone it updates, if it fails the check on 2 additional retries, BIND is restarted. But reason is unknown. To show how it is hitting us I ran a script which digs six statically defined records once a minute, it failed 56 times during 12 hours, there were several cases when they were not resolving for two minutes. | MAAS 3.3.5 We noticed in test runs that our staticaly defined VIP addresses for openstack services sometimes don't resolve and a minute later they are fine.
