So the interaction ...

1263466055492: conn#0 ch#1 -> 
1263466055507: conn#0 ch#1 <- 
content-encoding=null, headers=null, delivery-mode=2, priority=null, 
correlation-id=null, reply-to=null, expiration=null, message-id=null, 
timestamp=null, type=SupplierReleaseUpdate, user-id=null, app-id=null, 
1263466057457: conn#0 ch#1 -> 
1263466057457: conn#0 ch#1 -> 

... is the very last thing you see before it gets stuck? If so then that 
is very interesting since it would indicate that the server is failing 
to reply to the basic.get. Either that, or the reply from the server has 
gone astray.

The next step is getting your source code so I can try to reproduce your 
observations locally.

The message content is opaque to the server and the client library.

However, since you are running on Windows ... we have had some reports 
from people indicating that Windows may be interfering with XML 
payloads, resulting in all kinds of mysterious behaviours. So one 
possible thing to try is to encrypt your payloads.
