Our trace of the CacheManager management of the memory pool. The pool's size is
14mb.
TOTAL MEMORY is total used at that moment.
FULL MEMORY is the memory used by those objects marked as having reached 'full'
memory status.

> Project: Jackrabbit
> Issue Type: Bug
> Components: Jackrabbit API
> Affects Versions: 1.2.1, 1.2.2, 1.2.3, 1.3
> Environment: Tomcat 6.0, XP Pro w/1Gb

> Folks,
> We have been running tests on JCR v1.3 and v1.2.1 for the past two weeks. The
> system keeps running out of memory after X number of documents are added. Our
> initial test consisted of about 50 documents and gradually increased to about
> 150 documents. The size of the documents ranged from 1K to 9MB. We later
> changed the test to consist of files with less than 1K in length with the
> same result. Increasing the heap size delays the error but the outcome is
> always the same (Servlet runs out of heap memory.)
> Using JProbe we found a high number of references created by the caching
> sub-system (SessionItemStateManager.java, SharedItemStateManager.java,
> LocalItemStateManager.java). We changed the caching parameters using
> CacheManager (min 64K - max 16MB). This change only delayed the error.
> Servlet eventually runs out of heap memory.
> We are more than happy to share our findings (even source code and test data)
> with the Jackrabbit team. Please let us know how you wish to proceed.
> Sincerely,
> Antonio Carballo
