DNS records are not synchronized with the slave DNS servers. In the PBA-S container:
[root@pbas ~]# dig axfr domain.com @localhost .... .... ;; global options: printcmd ;; connection timed out; no servers could be reached
So zone transfers are prohibited in the PowerDNS server. Restarting pdns service fixes the issue:
# /etc/init.d/pdns restart
PBA-S is installed on the EOLed Virtuozzo 4.0.
Upgrade Virtuozzo on the management node to the version 4.7
Create periodic task on PBA-S node for restarting pdns service each hour with the following script (set the permissions to 755 for this script):
/etc/cron.hourly/pdns --->8--- #!/bin/sh /etc/init.d/pdns restart ---8<---
