Comment 9 for bug 1191768

I still seem to be hitting this or something related on 2013.1.3 using kombu/rabbitmq. I end up with stale entries in the dhcp hosts file:

fa:16:3e:33:6b:f4,host-10-5-0-1.openstacklocal,10.5.0.1
fa:16:3e:41:79:76,host-10-5-0-2.openstacklocal,10.5.0.2
fa:16:3e:93:21:e3,host-10-5-0-3.openstacklocal,10.5.0.3
fa:16:3e:ae:46:62,host-10-5-0-4.openstacklocal,10.5.0.4
fa:16:3e:f8:44:82,host-10-5-0-10.openstacklocal,10.5.0.10
fa:16:3e:e7:d0:3b,host-10-5-0-25.openstacklocal,10.5.0.25
fa:16:3e:b0:f1:f4,host-10-5-0-28.openstacklocal,10.5.0.28
fa:16:3e:05:e5:55,host-10-5-0-4.openstacklocal,10.5.0.4

Restarting the DHCP agent re-renders the file correctly:

fa:16:3e:33:6b:f4,host-10-5-0-1.openstacklocal,10.5.0.1
fa:16:3e:41:79:76,host-10-5-0-2.openstacklocal,10.5.0.2
fa:16:3e:93:21:e3,host-10-5-0-3.openstacklocal,10.5.0.3
fa:16:3e:05:e5:55,host-10-5-0-4.openstacklocal,10.5.0.4
