Connection leaks on JCA

[Yavuz Kavus]

Hi.
We are using jackrabbit on glassfish as jca adaptor.
The connection is gotten as :

            Context ctx = new InitialContext();
            repository = (Repository)ctx.lookup("jcr/Repository");
            //this session used throughout full request. (ThreadLocal)
            Session requestSession = ...;

After a while(usually 5 minutes) using connection, we are getting:

WARNING: A potential connection leak detected for connection pool 
jackrabbit-jca-pool.

Every taken session is being closed at the end of related request.

What may be the reason of the problem, any idea?

Thanks.
