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
