[jboss-user] [JBossCache] - JBoss Cache 1.4.1 SP3 | NodeLockingScheme

Thu Jul 26 07:54:02 EDT 2007

We are using JBoss AS 4.0.3 SP1 and JBoss Cache 1.4.1 SP3 and MySQL Server 50.18. We are using PESSIMISTIC 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:-
