Clustering WSO2 CEP 3.1.0 in full active-active mode with more than two members?

Question

I have followed the instructions here to cluster WSO2 CEP 3.1.0 in high availability, full active-active mode and it works great when there are two members.

When I add a third member to the WKA group, all members acknowledge each other but now a duplicate event is emitted.

Is it possible to run the CEP in high availability mode with more than two members? Cheers!

CEP 3.1.0 is only tested with two nodes, and we recommend you to use only two nodes for now. I have created a ticket to fix this in future releases. https://wso2.org/jira/browse/CEP-853
