WSO2 AM 1.6: Publish service to cluster

Question

We create and publish a service through the web console (/publisher). This is environment is a 2 node WSO2 AM cluster with a loadbalancer on top of it (HAProxy).

When we invoke the service (SoapUI), via this load balancer, one request succeeds and the next one fails and so on.

IMHO: The cluster configuration should be correct. I can see the published service on both nodes if I start the /publisher app on each node.

axis2.xml:
- Hazelcast clustering is enabled
- Using multicast

master-datasources.xml
- pointing to Oracle database

api-manager/xml
- pointing to jdbc string in master-datasources.xml

Does anyone have some tips.

It seems that the Synapse Artifact is not deployed on two Gateways correctly. Can you go to /repository/deployment/server/synapse-config/default/api and see if the both node have an xml file for the published API. If you haven't enabled Deployment Synchroniser the artifact will only be created in one node.
