Exactly octavia-health-manager will only create two subprocess. However there are 6 process of octavia-health-manager,this is not correct. And there is a error :[Errno 98] Address already in use. Obviously the reason is that
hm_listener_proc subprocess is still alive after restart the octavia-health-manager service. It still listen to port 5555.
