---------------------------------------
Thomas
We figured that it would be tough to reproduce. Let me see if we can produce
something simple on our end but it won't be any time soon.
==
As for the number of sessions, we believe that we have established by a myriad
of test cases that the problem is reproducible with one or more sessions.
Take care,

> 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
