We are using JBoss AS 4.0.3 SP1 and JBoss Cache 1.4.1 SP3 and MySQL Server
5.0.18. We are using OPTIMISTIC NodeLockingScheme currently.
We are getting various cache exceptions:-
1- DataVersioning
2- Duplicate Key
3- ReadWriteLock
Because of these errors, our production system gets down.
Here is the exception stack trace:-
