[jira] [Commented] (AMQ-3816) Broker does not retain messages for a STOMP durable consumer if the broker restarts while the consumer was running

["Buchi Reddy B (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMQ-3816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13276667#comment-13276667 ] 

Buchi Reddy B commented on AMQ-3816:
------------------------------------

@Timothy did you test this case with Perl code? I personally feel that there are some differences in Perl and Java STOMP implementations and some issues (like this one) might be real issues only in Perl STOMP clients.

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker, stomp
>    Affects Versions: 5.5.1
>         Environment: Perl STOMP clients on UNIX OS.

> We have noticed that the broker does not deliver some messages to a durable consumer in the following scenario.
> 1/ Start ActiveMQ broker, Perl STOMP producer on topics with persistence and Perl STOMP consumer with durable topics.
> 2/ Kill the broker while the consumer and producer are running.
> 3/ Kill the consumer. We have kept the producer running all these while.
> 4/ Restart the broker and producer will connect to it and continue to send the messages.
> 5/ Restart the consumer. We have noticed that the consumer was missing big chunk of messages sent by the producer when the consumer was down. But, we expect the consumer to receive these messages since it's a durable consumer and did not unsubscribe from these topics.
> I have enabled TRACE level logging for the broker and checked that the broker is recovering the durable subscription information from the kaha db logs when it restarts and marks the durable consumer as inactive durable subscription. However, broker does not seem to retain the messages for this durable consumer until the consumer comes up again.
> Is this expected? Does not broker guarantee message redelivery for durable consumers when the broker itself restarts?
> Please let me know if we have any configurations on the broker/client side to avoid these kind of issues.
