ofagent disconnects and reconnects with onos pods

[thomaslees]

I have created an ONOS cluster running as Kubernetes pods. I could connect ofagent with the cluster and could see my OLT in ONOS console with one master and two standbys. However when I 'watch roles' I can see the connection is lost every 30 seconds on both the standbys or so and is reestablished.
I am getting the following error in ofagent logs.

Any help will be highly useful
