                 Key: COCOON-2293
                 URL: https://issues.apache.org/jira/browse/COCOON-2293
             Project: Cocoon
          Issue Type: Improvement
          Components: * Cocoon Core
            Reporter: Krzysztof Kowalczyk


Invoking free on EHDefaultStore increase memory consumption and takes quite some time as described
in https://issues.apache.org/jira/browse/COCOON-2292. In our environment when we have 300
mb of free heap it is not enough to complete freeing of objects. But Ehcache can be configured
to clear memory store on flush, so when flush is invoked all elements from memory are removed.
This seems to have lower memory consumption and preserve cached elements (instead of permanently
removing them).

So it would be good to have a possibility to configure StoreJanitor for such behavior.
