When OpenStack API services are behind Apache2, HTTP Keep-Alive timeout is 5 seconds out of the box. Polling operations with the same interval as HTTP Keep-Alive timeout can cause intermittent failures like: Unable to establish connection to https://nova.example.com:8774/v2.1/servers/UUID: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response',)) Let's avoid the same value by default as Apache2's HTTP Keep-Alive timeout.
