Hazelcast Cluster Nodes don't show the same number of client sessions

Hi Gurus,

I need your Help!!!

I deployed 2 Windows Server 2008 R2 based Openfire servers 3.8.2 connected to a single MS SQL database(3rd server). The Openfire servers are clustered using the hazelcast plugin. Users and groups are pulled from AD. Java Max Memory has been increased to 1000MB. We currently have about 150 concurrent users per day.

The problem is every 2 to 3 days Client sessions in the Web Console won’t show the same number of sessions and cluster nodes on one server will show 3(one is idle) nodes instead of just 2. when this happens I also observed that Persistent group chats lose their history and users connected to one server can’t see users on the other. I would restart the Openfire service and the problem disappears but it returns after a couple of days. I have been looking around for a permanent solution to this. Have you had any similar issue? how did you fix it? I’d really appreciate the help…

Were you ever able to find a solution to this problem?
