A node is getting fenced after the rabbitmq-server resource is timing out on stop when a node leaves in a RHEL 7 Highly Available RHEL-OSP 6 cluster

Issue

• When a node leaves the cluster, another node reboots because its rabbitmq-server resource times out on a stop operation. Why is rabbitmq taking so long to stop?
• Why do my rabbitmq resource's operations take a long time to complete?
• When we reboot a node manually, another node's rabbitmq monitor operation times out causing all nodes to attempt recovery, and then one node gets scheduled for STONITH because its stop operation times out too.
