We create and manage MUC membership using the REST API plugin. We are seeing that some of the membership changes don't get reflected in Openfire even though the REST API call was successful. Most of the times this happens with removing members from the MUC. We are using Openfire 4.1.1 cluster with 2 nodes. I dont see any errors in the Openfire logs. Has anyone else seen similar issues? I would appreciate any pointers I can get.
