Hi,
I think i am dealing with a variant of this issue.
My Setup:
Openfire 3.9.3
user01: Spark
user02: Gajim, Gajim, Gajim (all of them with carbons enabled and set to the same priority)
user01 sends a message to user02 -> the three of the clients for user02 get the message.
when any of the clients for user02 tries to reply the message that one client goes offline.
I noted the same error reported by @Anders :
2014.10.10 10:42:42 org.jivesoftware.openfire.nio.ConnectionHandler - Closing connection due to error while processing message:
org.dom4j.IllegalAddException: The node "org.dom4j.tree.DefaultElement@70de9c7f [Element:]" could not be added to the element "forwarded" because: The Node already has an existing parent of "forwarded"
I tried with different combinations of clients for user02 to isolate the issue to the server software: (jitsi/gajim/yaxim , jitsi/gajim/gajim) and i got the same result, I noticed this happens when there are more than two sessions with carbons (same user), so the problem starts when a third session comes into place.
csh could it be related? if so, does the same fix apply?
Thanks,
