Public bug reported:

When restarting nova-network service, nova-network will initialize iptables and remove old rules, then add floating ip iptable forward rules one by one. 
If there are a lot of floating ips on one host, the process of adding floating ip rules could last several minutes.
This will cause the floating ips which last added iptable rules disconnected for that several minutes.
