Here's the log from <a href="mailto:rabbit@play.log">rabbit@play.log</a>. When play2 goes down and comes back<br>
up, the 'unit_test' queue (the only queue with messages) disappears.<br>

Just to confirm, the queues are mirrored across *three* nodes - play, play2 and util, right?<br>
<br>
The logs for play and util from around the same time might offer us some more clues.<span><font color="#888888"><br>
