Do I understand correctly that You have some memory leak in the neutron? If <br>
so, is it in neutron-server or neutron-l3-agent? And also, if that is true, <br>
can You open LP bug for that and provide some more info, like how many routers <br>
do You have there how to maybe reproduce it, etc.<br>
