The customer tried manually rebooting the node and that fixed the issue for a while and again it persists.
Followed the below steps to release the IP's but the issue is repeating:
- Unschedule the node and drain with `$ oc adm drain <node> --delete-local-data --ignore-daemonsets`
- then remove the "/var/lib/cni/networks/openshift-sdn/*" content:
- verified that IP's released and scheduled the node.
