Hello, I am running keycloak in cluster. I see following warn on start: WARN [org.jboss.as.txn] (ServerService Thread Pool -- 49) WFLYTX0013: The node-identifier attribute on the /subsystem=transactions is set to the default value. This is a danger for environments running multiple servers. Please make sure the attribute value is unique Should I care about it? I guess it is about distributed transaction? Keycloak does not use it?
