Sometimes during testing setup we can catch strange exception in client code

After some investigation we found that root cause is in KeepAlive options in wsgi template.
Here is the similar test case https://github.com/mikem23/keepalive-race
So we want to set "KeepAlive Off" in charm-nova-cloud-controller/templates/wsgi-api-os-compute.conf for this particular environment. |
