I am getting Possible Concurrency problem while using mod_jk with 2 instance of JBOSS 5.0.1 GA.
The Exact Warning message is:
problem: Replicated version id 7 is less than or equal to in-memory version for session MJdW5RBaJ-Wz0WW-arHG9g___ (as it is clusterd Session)
sticky session is set to 1 (True).
again Richfaces component , rich:tab is not working properly (it seem like it is not clickable but in the server log view session expired exceptions were occured) and give viewSessionExpired Exception when enabling cluster mode (enabling High Availbilty via mod_jk, <distributable/> tag).
javax.faces.application.ViewExpiredException: viewId: ... could not be restore.
whenever we start jboss alone everything is going fine.
