<track-connection-by-tx/> is available also to <connection-factories>
datasources, at least in JBoss 3.2.5 (do not know about 3.2.6). And it seems
that specifying it solves the problem, at least the test case I received
worked for 50 minutes without any exception in the log.

David, can we consider this JBoss/configuration issue or maybe there is
something to tune in JayBird?

Thanks!
