Hi, I am quite new to the JBossCache. We are using JBossCache as the Second Level Cache. I wanted to know the relation between Eviction Policy and CacheLoader I have a couple of questions: What exactly happens when the Eviction Policy is in place withoutthe CacheLoader configuration? What exactly happens when the Eviction Policy is in place with the CacheLoader configuration? With the following configuration it has eaten up all of the available virtual memory to the extent, where in it is unable to swap further. ? | <?xml version="1.0" encoding="UTF-8" ?> | <server> |
