> Key: JCR-4579
> URL: https://issues.apache.org/jira/browse/JCR-4579
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-data
> Reporter: Claus Köll
> Assignee: Claus Köll
> Priority: Major
>
> We are using a DriverDataSource and in really rare situations we see
> following exception
> {code:java}
> Closed Statement; nested exception is java.sql.SQLException: Closed Statement
> {code}
> The DriverDataSource uses the commons-dbcp library to create a
> BasicDataSource.
> The old commons-dbcp is also using a fairly old version of commons-pool.
> After researching a valid fix can be is to disable the pooling of
> PreparedStatements.
> As a quick fix i would define a SystemProperty to disable the pooling. We
> have a really high load and we see no performance impacts.
> As a future fix we can update to a actual dbcp2 version.
