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.

Please not that passivation is false
Please let know what happens with above config and so that I can configure in the right
manner.
Thanks,
