[rabbitmq-discuss] Order in Queues (FIFO)

[rabbit15]

Hi, I have question about order of messages in queues of RabbitMQ.

Here are my messages

1 {"timestamp":"2013-08-20
11:00:27","type":"published","node":"rabbit at debian","exchange":"FUS","queue":"none","routing_keys":["ctrl"],"properties":{"reply_to":"AVS","correlation_id":"0","content_type":"fuosn"},"payload":"AA=="}
2 {"timestamp":"2013-08-20
11:00:27","type":"received","node":"rabbit at debian","exchange":"FUS","queue":"FUSControlQ","routing_keys":["ctrl"],"properties":{"reply_to":"AVS","correlation_id":"0","content_type":"fuosn"},"payload":"AA=="}
3 {"timestamp":"2013-08-20

problem is that messages order is different while publishing and receiving,
not only in rabbit log but as well in applications using it (one connection,
one channel per both application)
eq. payload sent to rabbit in in order - line: 3, 4, 5
but receiving is in order line: 6(same msg as 4), 7(same message as 5), 8
(same message as 3) - which gives payloads order 4,5,3 

Cheers,
Artur
