Public bug reported:
Pre-conditions:
deploy a 3 controller openstack cluster with stable/rocky branch without using
docker, and enable l3 agent ha in configuration files: neutron.conf
l3_ha = true
max_l3_agents_per_router = 3
reproduction steps:
1. create a router and wait for neutron-keepalived-state-change and keepalived
becomes to running state. (on control-1)
2. stop the neutron-l3-agent on control-1, systemctl stop neutron-l3-agent
3. delete the router and wait for the process complete so that neutron router
show <router_id> report the router is non-existed.
4. start the neutron-l3-agent again on control-1 until neutron agent-list
reporting it alive
5. ps -ef | grep <router_id> , you will find neutron-keepalived-state-change
and keepalived still there and cannot be terminated anymore until we restart
the node.
