Comment 7 for bug 1338608

Reproduced on system test 'deploy_ha':
http://jenkins-product.srt.mirantis.net:8080/view/0_master_swarm/job/master_fuelmain.system_test.ubuntu.thread_5/151/

Same situation in the puppet-agent.log (node-1, 'slave-02_controller'):
(/Stage[main]/Osnailyfacter::Cluster_ha/Nova_floating_range[10.108.6.128-10.108.6.254]) Could not evaluate: Authentication failed with response code 504

Same situation in rabbitmq.log with connectivity errors:

2014-09-05T00:23:03.526999+01:00 notice: "broker forced connection closure with reason 'shutdown'",none}

Deployment of node-5 'slave-05_compute' failed before it even started (there is no puppet-agent.log on the node)

Also, while I was examining the logs, Fuel-UI shown that node-3 and node-5 went offline for a few minutes. But, actually, node-3 and node-5 was working all the time (I open VNC on it via vitr-manager and my session to the nodes wasn't broken)
