Timothy Bish closed AMQCPP-193.
-------------------------------
Resolution: Cannot Reproduce
> If activeMQ blocks due to reaching memory limit during a transaction, the
> last message sent is posted to the queue after the rollback occurs and
> persists
> ---------------------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: AMQCPP-193
> URL: https://issues.apache.org/activemq/browse/AMQCPP-193
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Openwire
> Affects Versions: 2.2, 2.3
> Environment: Solaris x86, Solaris Sparc (UltraSPARC-T1)
> Reporter: Brian Roach
> Assignee: Timothy Bish
> Fix For: 2.3
>
> Attachments: transactionTest.cpp
>
>
> If you send a large number of messages inside a transaction, and ActiveMQ
> runs out of memory, cms::MessageProducer::send() throws an exception (as it
> should).
> The exception text is: No valid response received for command
> The problem is ... the last message sent (the one that caused the exception
> to be thrown) gets added to the queue while the others are rolled back. This
> is a large problem, as the whole point of transactions is to avoid this sort
> of thing.
> To summarize:
> - Start sending messages with the session set to SESSION_TRANSACTED
> - Fill ActiveMQ memory
> - Receive exception
> - The last message sent will be in the queue. All other messages will be
> rolled back.
> Here's what the debug log looks like:
> DEBUG Usage - Memory usage change. from: 2, to: 1
> DEBUG AMQMessageStore - Transacted message add rollback for:
> 68445488-66bc-c258-0d30-4a1faede93a5:0:1:109, at: offset = 4527877, file = 6,
> size = 47444, type = 1
> DEBUG Usage - Memory usage change. from: 1, to: 0
> DEBUG AMQMessageStore - Transacted message add rollback for:
> 68445488-66bc-c258-0d30-4a1faede93a5:0:1:110, at: offset = 4575321, file = 6,
> size = 47439, type = 1
> DEBUG TransportConnection - Connection Stopped: /127.0.0.1:44382
> DEBUG AMQMessageStore - Journalled message add for:
> 68445488-66bc-c258-0d30-4a1faede93a5:0:1:111, at: offset = 4622760, file = 6,
> size = 47442, type = 1
> As you can see, it adds a message to the queue after the rollback and after
> stopping the connection.
> Attached is C++ that will demonstrate the problem.
