The Hazelcast setup is working great except for one minor issue, for some reason when users permissions are updated for a group chat room, they're not being replicated to the other servers in the cluster.
Right now we are using a single MySQL DB running version 5.1.62, CentOS 6.3, and Openfire 3.8.1.
I didn't want to post the entire hazelcast config, so if there is any relavant part of it that would be helpful, please let me know and I'll get it posted. 
Thanks for any help anyone can provide.
