<div>I think your question of "are the queues declared as HA" might be the key to this, though - from what I understand, the application itself (in this case, mcollective) would have to declare that at the time the queue is created, yes? I suppose I *can*
modify mcollective to do this, but I was hoping I didn't have to. Any pointers on how you would do that from, say, a ruby application? :)</div>
<div><br>
</div>
<div>I appreciate everyone's help with this. This same question has been asked a couple of times on the mcollective forums, to which R.I.Pienaar replies simply, "Use ActiveMQ," and that's not an option for me� so I thought I'd have more success asking the
question here.</div>

<div>You haven't said what your setup is. Are the nodes clustered? Are the queues declared as HA?</div>
