I am using monitoring service version 1.7.0 to save all chat history into database. and it works for single instance.
Now I have a one load balancer and 2 openfire instance. Some messages are saved with null stanza and some messages are saved with valid stanza.
I have also build monitoring jar from https://github.com/igniterealtime/openfire-monitoring-plugin/issues/19 url, but it also save some chat history with null stanza and some with valid stanza.
@akrherz any quick suggestion?
