Description ppecka 2010-05-17 15:00:56 UTC 
Description of problem:
regarding of posts under https://bugzilla.redhat.com/show_bug.cgi?id=557243, 
behaviour of clustered qpidd nodes with or without "--cluster-size" option changes appereance/doubling of messages over nodes, but not stated in documentation. 


Version-Release number of selected component (if applicable):
1.3beta

How reproducible:
100%

Steps to Reproduce:
1. run M clustered qpidd instances (for matter of simplicity only two Q1,Q2) WITHOUT option --cluster-size
2. send one batch consisting of N messages to Q1
3. receive ALL messages on Q2
  
Actual results:
on Q2 or Q1 will be M * N messages

Expected results:
on Q2 or Q1 we can read only N messages


Additional info:
this behaviour can be changed when using "--cluster-size" option


Is this behaviour expected?

Can you give a bit more detail on reproducing this? I started two brokers in the cluster, created a queue, connected to one node and sent 20 messages. connected to the other node and received the same 20 messages as expected. What am I doing wrong or what am I missing out?

i'm retesting right now, but still not able to reproduce again on 1.3beta
