I don’t have a fix for this, but I only experience it if I start two Openfire instances at the same time. If I start one, make sure it comes all the way up (e.g. it logs that it has formed a cluster in nohup.out), then I start the second instance, I don’t get this error.

If you get this error, it’s easy enough just to cycle the instances one at a time to clear it up.
