Doc Text:
A high memory consumption was observed, especially in large environments, which often led to out-of-memory issues. The main culprit was neutron-ns-metadata-proxy process, responsible for proxying metadata requests from the VM to Nova. neutron-ns-metadata-proxy is now replaced by haproxy which has a more lightweight memory footprint.

Description Daniel Alvarez Sanchez 2017-04-06 13:10:17 EDT 
+++ This bug was initially created as a clone of Bug #1438469 +++

Currently, neutron-ns-metadata-proxy process has a large memory footprint [0] and, in large environments this could lead to OOM killers.

Some weeks ago, we got a patch merged upstream that switched metadata proxy Python implementation to haproxy. This reduced memory consumption dramatically and backporting it to OSP10 would really help.
