            3. Verify Network
            4. Deploy cluster
            5. Verify networks
            6. Run OSTF
            7. Create 2 volumes and 2 instances with attached volumes
            8. Fill cinder storage up to 30%(15% for each instance)
            9. Shutdown of all nodes
            10. Wait 5 minutes
            11. Start cluster
            12. Wait until OSTF 'HA' suite passes << Fail
            13. Verify networks
            14. Run OSTF tests

OSTF fails while trying to authenticate

In ostf.log:
Authorization Failed: Unable to establish connection to https://10.109.13.3:5000/v2.0/tokens

In keystone-all.log:

unavailable: [client 10.109.11.5:38056] mod_wsgi (pid=7481): Unable to connect to WSGI daemon process 'keystone_main' on '/var/run/apache2/wsgi.7473.0.2.sock' after multiple attempts as listener backlog limit was exceeded.

Unfortunately environment with this test was cleaned up

Apparently MySQL crashed. Unfortunately, I can see the log file of the last run only.
Could you please reproduce it on the environment and ping me?

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
