Description Alan Conway 2013-12-13 19:43:58 UTC 
Description of problem:

When using standalone replication between two brokers, there will be replication errors if messages are put onto the primary queue before replication is set up.

Version-Release number of selected component (if applicable):


How reproducible: 100%


Steps to Reproduce:

Create queue "q" on brokers P and B.
Put messages 1,2,3 on P.q
Start replication from P.q to B.q
Put messages 4,5,6 o P.q
Fetch and acknowledged one message from P.q
Fetch all messages from B.q. 

Actual results:

B.q has messages 0,1,3,4,5

Expected results:

B.q has messages 1,2,3,4,5

Comment 3 Alan Conway 2014-04-04 21:09:40 UTC 
The docs are missing a configuration setting (on both brokers)

  ha-queue-replication=yes

I raised doc bug 1084621. There is more recent documentation here:
