Hi! I was building a cluster with pacemaker+pacemaker-remote (CentOS 6.5, everything from the official repo). While I had several resources, everything was fine. However, when I added more VMs (2 nodes and 10 VMs currently) I started to run into problems (see below). Strange thing is that when I start cman/pacemaker some time later - they seem to work fine for some time.
