Wade Poziombka commented on AMQ-2923:
-------------------------------------

I also observe this out of order behavior.  Is there any update or workaround?

>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.4.0, 5.4.1, 5.4.2
>         Environment: Ubuntu 10.04.
>            Reporter: James Green
>            Priority: Critical

> On a single host:
> Producer P1 posts message M1 to Queue Q.
> Producer P2 posts message M2 to Queue Q a few seconds later.
> Consumer C1 comes a few seconds further along along and begins reading from Queue Q. Occassionally, C1 receives M2 before M1.
> This is what I'm seeing in two PHP application connecting to ActiveMQ via STOMP. After dozens of tests I've finally reproduced it with trace=true. I am not sure what environmental conditions cause this to occur.
> I will attach a log. Watch for destination:/queue/Outbound.Account.200000 which is Q. M1 has a reason="MJINITIALSTATE" and M2 has a reason="E----:Confirmed..."
