Wildfly 10.1 + mod_cluster 1.3.1 - Session replication problem

Hi,

I'm trying to follow Clustering and Domain Setup Walkthrough - WildFly 10 - Project Documentation Editor but the final result is not as expected.

Now I'm with a Ubuntu 16.04 - Wildfly 10.1 as master, Ubuntu 16.04 - Wildfly 10.1 as slave and CentOS 7 with mod_cluster 1.3.1 all in separated machines.

My problem:

The cluster replicate the application to slave but not the session .

mod_cluster-manager page display all expected information and I don't understand what is happen.

Can someone help me?

Hi Diego, node registration in mod_cluster console is not indication that the backend cluster has formed. Can you check you logs to see if the nodes "see" and communicate with each other? If not, most frequent problems are setup firewall, disabled multicast (which is the default mechanism for node dicovery) or wrong test.

Hi Radoslav,
the communication between nodes apparently are correct because the application are being balanced when one of the nodes is down.
