Hi,
I have just deployed a cluster (hazelcast v2.2.0) of Openfire server (v4.0.3) on my 3 CentOS servers.
I have also deployed another standalone Openfire server which plays the role of external server which etablished a S2S session with one node of the cluster.
All work fine except one thing : when I restart service on one node the S2S session seems to be broken with standalone server and client (Spark v2.6.3) which is connected on it can not join again "conference.<domain>" host by cluster.
The only thing that permits to have a steady situation is to disconnect S2S session through web interface on the server which have etablished the session on first.
For example, if the standalone server is the first which etablished a session with one node of the cluster I must disconnect the S2S from web interface of standalone node on "sessions/server sessions" menu (and vice versa).
Why S2S session can not be etablished again ?
Any help would be appreciated
