I removed the corosync (1.x) and pacemaker packages and built Corosync 2.3 and Pacemaker 1.1.9 from source. It generally seems to run better but I am having big issues with Corosync. I have 14 completely identical nodes. They differ only in ip address and host name. Periodically, corosync will fail to start up on boot. It's not consistent and happens randomly. What's even worse, once the cluster is up Corosync will occasionally die for no apparent reason. There are not errors logged. Nothing. The process simply disappears, taking the node offline.

Corosync has a blackbox - did you interrogate that too?
