Last value queue missing messages.

[black_ice]

Hello. Using HornetQ 2.1.1 FInal on JBoss AS 5.1

I *now yes* have a concrete problem with last value queue. I dont know if its a configuration issue or a possible bug or that last value queue shouldnt be used while consuming.

I added 200 objects with the _HQ_LVQ_NAME. =1,2,3....20 and  only 20 are on the queue. Thats OK.

But now i add a consumer. Consume one and buffer those 20 objects (they are on delivery,use a sleep after getting the first one). Queue MessageCount=20, Queue Delivering = 20. Consumer count=1:

Now i add 200 objects with the _HQ_LVQ_NAME = 1Hi,2Hi,3Hi...20Hi. They wont get into de queue, if i look into server's log it says-

Error (LastValueQueue) Failed to ack old reference.

Java.lang.IllegalStateException: Cannont find add info 6455...

<-- it seems that insertion thread crashes and message gets lost.

Someone also having this behavieour?

Thanks.

PS: in test code fix imports (Inicio = producer and Inicio_1=consumer). Change the _HQ_LVQ_NAME property after one execution so you see how different ids dont get into the queue.

As explained on the wiki, please make sure you have tested this against TRUNK and please submit a self contained test program that we can just run, no having to set up servers, tweak java files etc.

Take a look at LVQTest as an example of the sort of test program using the core API.

Ok excuse me, im starting @ this world, ill be doing it now, will report asap.

(After the consumer timeouts the messagecount its -182 :/)

Ok, tested with last trunk.

It seemed to be fixed on my test, but my real environment its still losing em, will redo test @ monday. But after closing consumer message and delivering count are still crazy (going negative and such, not like a problem for me but well)

My job time its ending. If i cant now ill upload the test program next monday (ive tested with my crap javas and have to look at test cases).
