Description (partial)

When ESC is deployed as an A/A cluster, the current leader node can unexpectedly loose leadership role when the cluster is managing a large number of VNFs (> 3500).  This causes a leadership transfer to another cluster node.  The new leader successfully assumes the cluster leadership role; the previous leader remains operational in follower role.  

While the leadership switch is being performed new service requests from the NB interface can not be serviced.

When this condition

This behaviour has been observed when the NB (ETSI) performs a bulk query of all deployments (e.g. via /vnflcm/v1/vnf_instances).
