hi Eugen,

The current setup is 3 controller nodes,  The Load is not much  on each
controller and the number of DHCP agent is always set to 2 as per the
standard in the neutron.conf, The L3 agent seems to be stables as other
router namespace works fine under it, Only few router  Namespace get
affected under the agent.

Most of the template having issue , Have all instance having FLoating IP, a
Stack with a single floating IP have chance of issue very less
