There is a significant delay during DNS records data propagation between two or more NS servers registered in OSA system.

Comparing the DNS zone details of some updated zone reveals that new data is still missing on one of the DNS servers, which causes a delay in DNS resolution of the update domains.

Update PowerDns or Update named tasks are scheduled on constant basis every 5 minutes.


The system is currently under increased load of DNS updates, and the events are getting queued up, delaying the timely propagation of DNS records. The default behavior of the DNS service controller is to process 20 DNS zone updates every 5 minutes.


It is possible to change the default interval of scheduling DNS update tasks and make it lower than 5 minutes.

CAUTION: the change may bring additional load on the system and lead to degraded performance. It is not recommended to apply the changes on permanent basis.

The following scripts may be used to commit the change:

Example of script usage:

# python 60

The command will change the interval of DNS zone updates from default 5 minutes (300 seconds) to 1 minute (60 seconds).

It is required to restart OA service to commit the change afterwards.

OA >= 7.0

# service pa-agent stop
# service pa-agent start

OA < 7.0

# service pem stop
# service pem start
