We're trying to set up Midpoint in a clustered configuration. We are using Postgres as the database.

In Midpoint's config.xml I have added the following:
<taskManager>
        <clustered>true</clustered>
</taskManager>

In Tomcat's Catalina.properties I've added the following
midpoint.nodeId=server1
midpoint.jmxHostName=172.21.13.1
com.sun.management.jmxremote.port=20001

This produces the following error:
2017-06-29 10:17:11,346 [] [ClusterManagerThread] ERROR (com.evolveum.midpoint.task.quartzimpl.cluster.NodeRegistrar): Cannot update registration of this node (name server1, oid bfbdff25-c7e2-4491-a79d-219787882b25), because it does not exist in repository. It is probably caused by cluster misconfiguration (other node rewriting the Node object?) Stopping the scheduler., reason: Object of type 'NodeType' with oid ' bfbdff25-c7e2-4491-a79d-219787882b25' was not found. (class com.evolveum.midpoint.util.exception.ObjectNotFoundException)

When I first start the node, the m_node table in our database seems to contain the node's information correctly. Then, about 45 seconds to a minute after the node has started, the node seems to forcibly restart itself (Displaying the welcome message once again in the logs) and the oid in the table is overwritten with a random different ID to the one mentioned in the error message, thought Midpoint still seems to expect to find the original one (which is inserted correctly before the apparent restart, and rewritten after it). This happens whether or not the other node is powered on.

Thanks,
