Subject [jira] Created: (JCR-619) CacheManager (Memory Management in Jackrabbit)

CacheManager (Memory Management in Jackrabbit) 

                 Key: JCR-619
                 URL: http://issues.apache.org/jira/browse/JCR-619
             Project: Jackrabbit
          Issue Type: New Feature
          Components: core
    Affects Versions: 1.1
            Reporter: Thomas Mueller
         Attachments: cacheManager.txt

Jackrabbit can run out of memory because the the combined size of the various caches is not
managed. The biggest problem (for me) is the combined size of the o.a.j.core.state.MLRUItemStateCache
caches. Each session seems to create a few (?) of those caches, and each one is limited to
4 MB by default.

I have implemented a dynamic (cache-) memory management service that distributes a fixed amount
of memory dynamically to all those caches.

Here is the patch
