Public bug reported:
Steps to reproduce:
0. The issue is noticeable at scale (100+ nodes), DVR should be turned on
1. Run rally scenario NeutronNetworks.create_and_list_routers
Initially neutron-server processes consume 100-150M, but at some point
the size rapidly increases in several times. (At 200 nodes the raise was
from 150M to 2G, and upto 14G in the end).
The issue may lead to OOM situation causing kernel to kill the process
with highest consumption. Usually candidates are rabbit or mysql. This
makes cluster completely inoperable.
