Broadcast messages are sometimes duplicated/triplicated
A user reports and even I see this on igniterealtime.org's Openfire. The broadcast message is somethings received twice or three times. I do not always reproduce this issue though. Personally, I have only tried using the broadcast message tool on the admin console.
My bet: Carbons. We send the message to each users' clients and it's then copied to each of the other clients.
This continues to happen with igniterealtime's openfire and can't figure out why
