>                 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
>              Labels: candidate_jcr_2_14
>             Fix For: 2.22, 2.16.7, 2.21.2, 2.20.2
>
>
> 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.
