Ricardo,
Are all tasks being closed? Are you using runandrender task or run task
followed by render task?

Are you using the Graphical query builder in your datasources or the
normal jdbc datasource. I think this error message needs to be logged
as a bugzilla entry. Any chance you could do that?

Can you post the code you are using? Are you using runandrender task or
separate run and then render task?

Are you having this issue?
This looks to me like task where not being closed or the rptdocument not
being closed.

If you are using the WebViwer the documents should be getting closed
automatically.
