scope of openfire consultation work:
(1) whether we should migrate openfire from 3.x to the latest. We use several plugins, and modify some files from openfire. The upgrade will require quite a lot of efforts.
(2) evaluate openfire 1:1 chat vs room communication. We did move from 1:1 chat to xmpp room and then encountered issues.
(3) openfire jvm optimization, and debug outofmomory issue: could not create native thread (from nowhere, thread count increased from 200 to 30k)
(4) diagnosis client connection issue: client connection on and off; sometimes no client can connection
(5) openfire cluster setup: we have 2 instances now. How can we scale to more instances or any limitation.
