[jira] [Created] (APLO-215) Broker may send queued messages
multiple time over SSL
Lionel Cons created APLO-215:
--------------------------------
Summary: Broker may send queued messages multiple time over SSL
Key: APLO-215
URL: https://issues.apache.org/jira/browse/APLO-215
Project: ActiveMQ Apollo
Issue Type: Bug
Environment: apollo-99-trunk-20120621.153441-53
Reporter: Lionel Cons
When putting messages in a queue and removing them with client side acknowledgments, Apollo may send some messages multiple times. Here is an example test output:
$ perl test.pl
producing 3000 messages... done
consuming 1000 messages... done
consuming 1000 messages... done
consuming 1000 messages... done
draining... drained 13 messages
message 1000 received 2 times!
message 1994 received 2 times!
message 1995 received 2 times!
message 1996 received 2 times!
message 1997 received 2 times!
message 1998 received 2 times!
message 2988 received 2 times!
message 2989 received 2 times!
message 2990 received 2 times!
message 2991 received 2 times!
message 2992 received 2 times!
message 2993 received 2 times!
message 999 received 2 times!
done checking
The consumers are careful with client side acknowledgment so there should be nothing left for the final drainer.
Please see the attached script for more details. You may need to play with the number of messages or the number of consumers.
Note that the test script seems to work fine over STOMP. I've only seen problems with STOMP+SSL.

Lionel Cons commented on APLO-215:
----------------------------------
In this scenario, you are right that adding a receipt header on the DISCONNECT frame does fix the problem. I will trigger a discussion on the STOMP spec list to draw more attention to this practice.
However, I still have similar problems with topics that do not go away that easily. I will open a new issue for these.

Hiram Chirino commented on APLO-215:
------------------------------------
I think this may be occurring because you close out the consuming connection before you verify that those ACKS have been fully transmitted to the server. Try adding a receipt header on the DISCONNECT frame and wait for that come back before closing the socket out.
