> Key: ARTEMIS-1570
> URL: https://issues.apache.org/jira/browse/ARTEMIS-1570
> 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
> Attachments: SharedNothingReplicationTest.java
>
>
> 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.
