We have httpd 2.2.26 on RHEL 6.8
I have installed Jboss EAP 6.4 in Domain Mode.
with mod_cluster/1.2.11.Final

My Jboss domain is working, I can deploy, login to management console, see my servers/deployment, etc.
I can also browse to my mod_cluster. Here I can see information from my virtualhosts.

The issue is that the mod_cluster will not discover the nodes.

It should be known that I was able to successfully get this working on another server.

I have tried many different configurations to get it working, but it just doesnt work.

Current Configuration though is:
LoadModule proxy_cluster_module modules/mod_proxy_cluster.so
LoadModule slotmem_module modules/mod_slotmem.so
LoadModule manager_module modules/mod_manager.so
LoadModule advertise_module modules/mod_advertise.so
