I don't see anything wrong with your configuration, except one comment: unless
you are running distributed databases, you really don't need XADataSource, just
DataSource is fine. That might save you some troubles, in case your JDBC
driver has bugs in connection handling for 'multi-database' setup (I am not
familiar with postgresql).
Again, the result of CMP failure does not mean CMP is the cause of connection
leaks.

Hrmmm
Maybe I have resin configured wrong then, because this did not occur in resin
2.1.17 would you mind taking a look?

Most likely the other parts of your code are leaking the DB connections. CMP is
not likely the source of leak.
We use CMPs extensively, our site is stable, with an over $10 million worth of
single day on-line transactions.
We are currently running resin 3.0.22.

Subject: [Resin-interest] CMP 2.1 Relationship Not Closing Connections
My name is Tim Riley and I currently upgrading from 2.1.17 to 3.0.23 and I use
CMP 2.1 (EJB 2). I do not want to upgrade from EJB 2 to EJB 3 however I ran
into this issue http://bugs.caucho.com/bug_view_page.php?bug_id=1286. Does
anyone know if there is a work around to this issue or if it is planned to be
fixed in an up coming release. I am also using Postgresql 8.1.
Thanks
Tim
