Oracle AQ: Message not removed from source queue after propagation

Question

Hi.
I have been playing around with a test setup for a "fanning out"-propagation system.
I have created three queues, SRC_Q, DEST_Q and DEST2_Q.
The propagation seems to work fine, the messages that I put on the SRC_Q get propagated to the destination queues. However, after propagation the message does not get removed from the source queue. Could anyone tell me why?
I am using Oracle 10g.
Here is my setup:
--Test payload
CREATE OR REPLACE TYPE test_payload AS OBJECT(
test_id NUMBER,
test_dt DATE);
commit;
DECLARE
subscriber SYS.aq$_agent;
BEGIN
--- Create Originating Queue and start it
DBMS_AQADM.create_queue_table( queue_table => 'SRC_MQT', queue_payload_type => 'Test_Payload',
multiple_consumers => TRUE );
DBMS_AQADM.create_queue( 'SRC_Q', 'SRC_MQT' );
DBMS_AQADM.start_queue( queue_name => 'SRC_Q' );
--- Create Destination Queue and start it
DBMS_AQADM.create_queue_table( queue_table => 'Dest_MQT', queue_payload_type => 'Test_Payload',
multiple_consumers => TRUE );
DBMS_AQADM.create_queue( 'Dest_Q', 'Dest_MQT' );
DBMS_AQADM.start_queue( queue_name => 'Dest_Q' );
--- Create Destination Queue2 and start it
DBMS_AQADM.create_queue_table( queue_table => 'Dest2_MQT', queue_payload_type => 'Test_Payload',
multiple_consumers => TRUE );
DBMS_AQADM.create_queue( 'Dest2_Q', 'Dest2_MQT' );
DBMS_AQADM.start_queue( queue_name => 'Dest2_Q' );
--- Add Subscribers and schedule propagation
subscriber := SYS.aq$_agent( 'test_sub', 'Dest_Q', NULL );
DBMS_AQADM.add_subscriber( queue_name => 'SRC_Q', subscriber => subscriber , queue_to_queue=> TRUE);
subscriber := SYS.aq$_agent( 'test_sub2', 'Dest2_Q', NULL );
DBMS_AQADM.add_subscriber( queue_name => 'SRC_Q', subscriber => subscriber , queue_to_queue=> TRUE );
--Propagation to queues
DBMS_AQADM.schedule_propagation( queue_name => 'SRC_Q', destination_queue => 'Dest_Q' );
DBMS_AQADM.schedule_propagation( queue_name => 'SRC_Q', destination_queue => 'Dest2_Q' );
commit;
END;
--Put something on the queue
DECLARE
message_handle RAW( 16 );
MESSAGE test_payload;
nq_opt dbms_aq.enqueue_options_t;
nq_pro dbms_aq.message_properties_t;
begin
nq_opt.visibility := dbms_aq.immediate;
nq_pro.expiration := dbms_aq.never;
MESSAGE := test_payload( 2, SYSDATE );
DBMS_AQ.enqueue( 'SRC_Q', nq_opt,nq_pro,MESSAGE, message_handle );
COMMIT;
END;
I am really stuck with this problem so I really hope somebody have some advice on what I am doing wrong.

I am also facing a similar issue. I have a multiconsumer queue. The message has been dequeued but the message is still present in the queue table and the message is also present in AQ$<queue_name> and the state is being shown as 'processed'.
This all was working fine few days back and somehow stopped working all of sudden. The DB version which I am using is - 11.1.0.7.0. Any help related to this will be greatly appreciated
