4.3. Communication Issue after Node Host Reboot

After rebooting a node host, the rhc app create command can fail to create an application, resulting in the following error: 
An error occurred while communicating with the server. This problem may only be temporary. Check that you have correctly specified your OpenShift server
'https://broker.example.com/broker/rest/domain/domain-name/applications'.

However, when verifying MCollective connectivity, oo-mco commands on the broker host may continue to find the rebooted node host without any issues: 
# oo-mco ping
	
node.example.com                         time=170.19 ms

The application creation failure can be due to a communication issue between ActiveMQ on the broker host (or dedicated ActiveMQ broker, if applicable) and MCollective on the rebooted node host. To resolve this issue, restart the activemq service: 
# service activemq restart
