Blocking Stored Procedure leaves an opened session

Hi Everyone,
Please, help me resolving the following problem: I have a blocking stored procedure that runs on the database (waits for new entries in Advanced Queue) and leaves an opened session even if the owner thread exits.Please, tell me how I can configure my database to return from this stored procedure if no message arrives (DBMS_AQ.ENQUEUE action) in a specified time. Thanks a lot for your reply,
