Remount attempt in Oxygen three node cluster results in unsuccessful initial read issued by vpp renderer

Environment: three oxygen nodes in cluster on Centos

These are the steps I'm doing:

1. mount 5 devices into /config/network-topology:network-topology/topology/topology-netconf/ with this configuration:

{ "netconf-node-topology:between-attempts-timeout-millis": 10000, "netconf-node-topology:connection-timeout-millis": 10000, "netconf-node-topology:default-request-timeout-millis": 10000, "netconf-node-topology:host": "192.168.10.26", "netconf-node-topology:keepalive-delay": 0, "netconf-node-topology:max-connection-attempts": 10, "netconf-node-topology:password": "admin", "netconf-node-topology:port": 2831, "netconf-node-topology:tcp-only": false, "netconf-node-topology:username": "admin", "node-id": "overcloud-novacompute-0.opnfv.org" }

this mount works fine, vpp renderer reads interfaces successfully
2. delete these five mounts
3. remount the 5 devices the same way and vpp renderer fails to read interface configuration from any of the devices
