Upon restart a failed node sees stale persisted SFSBs
-----------------------------------------------------
Key: EJBTHREE-1136
URL:
http://jira.jboss.com/jira/browse/EJBTHREE-1136
Project: EJB 3.0
Issue Type: Bug
Components: Clustering
Reporter: Brian Stansberry
Assigned To: Brian Stansberry
Fix For: AS 4.2.3.GA, HEAD
StatefulTreeCache needs to always purge all state in its region (including passivated
sessions stored by the cache loader) as part of initialize processing. It purges as part
of stop() but that's inadequate, as stop() isn't called when a node crashes.
Effect here is if buddy replication is used and a crashed node is restarted, the buddy
group tree state transfer doesn't override the old persistent state in the main tree.
If a failover request then comes in for a session previously persisted in the main tree,
instead of gravitating the data from the current owner the stale data is read from disk.
