[Anastasia Palkina]

1. Create new environment

4. Add 5 controller, 2 compute, 1 cinder, 2 mongo
5. Move Management network to eth1
6. Move Storage network to eth2 and untag it
7. Deploy the environment. It was successful
8. Deployment finished at September, 11
9. Run OSTF tests at September, 14
10. When 'Functional tests' was running, keystone became not available for some minutes. After it keystone works again

There are no errors in keystone logs. But 'crm status' shows many failed actions with mysql

[Boris Bobrov (bbobrov)]

keystone failed a lot of times with error http://paste.openstack.org/show/461406/

The error message shows that something has happened to MySQL during the tests.

Vladimir Kuklin said that cause is my overloaded environment. Users will not create such environment.
