'console' co is degraded on 4.12.0-rc cluster on Power.

Console CO degraded after 2 days, with this message "ConsoleNotificationSyncDegraded: Timeout: request did not complete within requested timeout - context deadline exceeded"

Reproducible on all clusters with the 4.12.0-rc builds.
https://mirror.openshift.com/pub/openshift-v4/ppc64le/clients/ocp/

Note:
1. This issue is seen on 4.12.0-rc clusters (rc.0, rc.1, and rc.2) with master nodes deployed with 16GB RAM.
2. 32GB RAM clusters are running fine
3. Post-deployment, all COs are good, but the console CO gets degraded after 3-4 days
4. Issue is not seen with ec builds ( we have a good ec.5 cluster which is running for a month)

1. Deploy OCP cluster using 4.12.0-rc build on Power Platform (ppc64le)
2. Check the status of all the nodes, co, and pods.  
3. Monitor the cluster for a few days.

"console" co goes to a degraded state. Error message "ConsoleNotificationSyncDegraded: Timeout: request did not complete within requested timeout - context deadline exceeded"

The cluster should stay stable.

The console operator does not seem to come out of degraded state, even though I have deleted the pod and there are no issues currently.


[root@rdr-praj-412rc2long1-syd05-bastion-0 ~]# oc get pods -n openshift-console

And yet, the status still shows as degraded.
