Why do I see "Attempt to close an unopened CCS descriptor" and "Error while processing disconnect: Invalid request" during or after a fence event in my RHEL 5 cluster?

Issue

• What does the following message mean while fencing a node?

Jun 13 16:58:42 node1 fenced[18797]: fencing node "node2"
Jun 13 16:59:14 node1 ccsd[18767]: Attempt to close an unopened CCS descriptor (2160).
Jun 13 16:59:14 node1 ccsd[18767]: Error while processing disconnect: Invalid request
Jun 13 16:59:14 node1 fenced[18797]: fence "node2" success

• Should I be concerned when I see messages regarding "Attempt to close an unopened CCS descriptor" during fencing?
• Fencing is failing after a ccsd "Invalid request descriptor" error when I have multiple devices in the same fence method.
