Acutally the combination of eviction policy plus cache loader is what we call passivation. Only when you evict the data, do you then store it to the loader store. So the cost is not as much as you think. If you just want to get around this problem, you can set the eviction policy to very long period such that it'd never trigger it. But you will get get event notification. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3974718#...
