Honeycomb mounting sometimes fails in Oxygen

This doesn't happen everytime.

The environment is Oxygen three node cluster.

Node mount 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": "HBfU1gKHExw89lMB3juq1g==", "netconf-node-topology:port": 2831, "netconf-node-topology:tcp-only": false, "netconf-node-topology:username": "HBfU1gKHExw89lMB3juq1g==", "node-id": "overcloud-novacompute-0.opnfv.org" }

Attached log corresponds to one of our nodes being stuck in connecting state:
