If you set the persistence property
and run "identity" test suite, it will get so far and then hang. This is because with this property set if a PM grabs a connection it will hang on to it until the PM is closed. If, for some reason, the developer doesn't close a PM the connection is left hanging. Eventually the application will run out of connections.
The tests that leave connections open need identifying and fixing. As a way of doing this you can set property
and then print out the number of active connections for a PMF via
