JBoss and httpd are failing to join together due to "client denied by server configuration"
Issue
- JBoss and httpd are failing to join together through mod_cluster.
- From the EAP 5 logging, we see:

- Or on EAP 6:

- Or on EAP 7:
ERROR [org.jboss.modcluster] (UndertowEventHandlerAdapter - 1) MODCLUSTER000042: Error null sending INFO command to machinename/x.x.x.x:6666, configuration will be reset: null
- And on the Apache side:
