> URL: http://jira.dspace.org/jira/browse/DS-320
> Project: DSpace 1.x
> Issue Type: Bug
> Components: XMLUI
> Affects Versions: 1.5.2
> Reporter: Flávio Botelho
> Priority: Blocker
> Attachments: dspace_context_finalize.patch,
> dspace_statement_closed_problem_XMLUI.txt

>
> We have been restarting Tomcat daily now, sometimes multiple times a day, the
> connections are running out.
> From a heap dump its clear that there is a lot of Context objects not being
> released, actually being hold onto by Finalizer.
> When applied Mark Woods patch:
> http://jira.dspace.org/jira/browse/DS-253
> That seemed to make it longer for the problems to appear, but still they end
> up happening. (Nevertheless the patch brings other concurrent critical
> problem from cocoon, that we never actually spotted in production).
> There are some Exceptions appearing before the one about no connections left,
> but the most common one is:
> Caused by: org.postgresql.util.PSQLException: This statement has been closed.

> org.dspace.storage.rdbms.DatabaseManager.querySingle(DatabaseManager.java:302)
> But i don't know why this is happening? Any clues?
> Anyways, maybe there is some problem with the top-level Exception handling in
> XMLUI that is ending up making Contexts getting 'leaked'?
