Comment 3 for bug 1321833

This message about lockfile is not a problem. Here is the real problem that breaks deployments (from puppet-apply.log):

And there are a lot of such errors for all nodes. Those errors mean you have some intermittent issues with Fuel admin network (the one where eth0 interfaces of your servers are connected to) - please check your switch and cables. You can also check logs on the Fuel node for any errors like "eth0: link is not ready".
