>                 URL:
>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 2.4.0
>         Environment: i'm running unit test on windows.
>            Reporter: shoukun huai
>            Priority: Critical
>             Fix For: 2.5.0
>         Attachments:
> I try to test replication when live is in heavy IO load.
> Attached is my junit test.
> The test use a slow message persister to simulate live is busy on IO, so JournalImpl's
`appendExecutor` is busy.
> After start live server, send 5 messages each with a property `delay` of 5000 ms, then
start the backup server, wait until it is replicated. Then send more messages without delay.
> Stop live and backup after all message sent, then check message journal.
> Backup will miss 2 message/journal entry.
