We’re seeing a strange behavior with certain customizations in Jicofo.
When calling setConferenceProperty (which calls sendPresenceExtension) from within processOtherPresence, we subsequently see presences from participants (not focus) being received, then again passed into processOtherPresence. This creates a high risk of infinite loops.
Looking after setConferenceProperty usages I don’t see how this flow could happen. You can try enabling XMPP traffic logging in Jicofo and once you have a specific example we can try to figure out if it’s a real issue.
