2016-10-12 10:04:38.587 25667 ERROR neutron.agent.l3.agent
IpTablesApplyException: Failure applying iptables rules
for example,this ERROR information will fill l3-agent log file
continuously until solving the problem ,it will fill the log file
space.
because we resyc the ERROR update into the queue when the update is
not been handle successfully.then the greenthread in l3-agent will
deal with the update periodicly,so print the log periodicly, but the
l3 agent has been deal with this update,wo should delete this update.
we could disable l3-agent in a networknode in ha model, then create
router,then restart the l3-agent ，we will see this problem。
