Description Gordon Sim 2009-11-06 11:31:20 UTC 
Description of problem:

If an acquired message is released, it is requeued in such a way that subsequent browsing of the queue is affected. This is a result of it being requeued in the wrong position in the queue.

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

qpidd-0.5.752581-30.el5

How reproducible:

100%

Steps to Reproduce: (using attached example programs)
1. for m in aaa bbb ccc; do echo $m; done | ./send
2. ./example3
3. don't process aaa, do process bbb, don't process ccc; then ctrl-c to exit
4. restart: ./example3
  
Actual results:

Only see ccc until that is consumed

Expected results:

Should see both aaa and ccc.
