Detailed bug description:
During rally scenario http://paste.openstack.org/show/497466/ we have faced with the following rally error: http://paste.openstack.org/show/497475/

Steps to reproduce:
1. Fuel 9.0-308 has been deployed
2. curl -s 'https://review.openstack.org/gitweb?p=openstack/fuel-web.git;a=patch;h=6106dfa026b042dac26ed77354321115b78aae5b' | patch -b -d /usr/lib/python2.7/site-packages -p2
rpm -Uvh epel-release-latest-7.noarch.rpm
sed -i s/^enabled=1/enabled=0/g /etc/yum.repos.d/epel.repo
yum --enablerepo=epel install uwsgi uwsgi-plugin-python python-uwsgidecorator
service receiverd restart && service nailgun restart
due https://bugs.launchpad.net/fuel/+bug/1569859 and https://bugs.launchpad.net/fuel/+bug/1570509
3. fuel-agent and fuel-library have been updated: http://paste.openstack.org/show/496825/ due https://bugs.launchpad.net/fuel/+bug/1543233 and https://bugs.launchpad.net/fuel/+bug/1574999
4. patch has been applied to keep rotated logs http://paste.openstack.org/show/495857/
5. patch has been applied to increase rsyslog chunks http://paste.openstack.org/show/496901/
6. LMA, ElasticSearch, Grafana plugins have been installed:
yum -y install createrepo rpm rpm-build dpkg-devel git
easy_install pip
pip install fuel-plugin-builder
git clone https://github.com/openstack/fuel-plugin-lma-collector.git
fpb --check ./fuel-plugin-lma-collector
fpb --build ./fuel-plugin-lma-collector
fuel plugins --install ./fuel-plugin-lma-collector/*.noarch.rpm
git clone https://github.com/openstack/fuel-plugin-elasticsearch-kibana.git
fpb --check ./fuel-plugin-elasticsearch-kibana
fpb --build ./fuel-plugin-elasticsearch-kibana
fuel plugins --install ./fuel-plugin-elasticsearch-kibana/*.noarch.rpm
git clone https://github.com/openstack/fuel-plugin-influxdb-grafana.git
fpb --check ./fuel-plugin-influxdb-grafana
fpb --build ./fuel-plugin-influxdb-grafana
fuel plugins --install ./fuel-plugin-influxdb-grafana/*.noarch.rpm
patch -b -d /var/www/nailgun/plugins/lma_collector-0.10/ -p1 < lma.patch (http://paste.openstack.org/show/495328/)
fuel plugins --sync
7. deployed cluster: 3 controller, 20 computes+ceph, 172 computes, vxlan+dvr, ceph for all
8. applied https://review.fuel-infra.org/#/c/20466/ on each controller node and restart apache
9. change /etc/haproxy/conf.d/020-keystone-1.cfg and /etc/haproxy/conf.d/030-keystone-2.cfg - commented out (due https://bugs.launchpad.net/fuel/+bug/1582202):
  #stick on src
  #stick-table type ip size 200k expire 2m
restarted haproxy via corosync
9. perform rally
Expected results:
 rally test passed
Actual result:
 rally test failed
Reproducibility:
 each time
Workaround:
 reduce rps parameter
Impact:
 keystone performance
Description of the environment:
- Operation system: ubuntu
- Versions of components: mos9.0
- Reference architecture: 3 controller, 20 computes+ceph, 172 computes, vxlan+dvr, ceph for all
- Network model: vxlan+dvr
- Related projects installed: LMA
