<div>Actually, I lied. This change has been merged and is part of Icehouse.</div>

</div>
<div>We are still running on Havana, though, and haven’t actually tried it. People we talked to have had success with it, though.</div>

<div>We see the same behavior, and a lot of other people have this problem, too. It’s related to how the Rabbit client code is handling disconnects/reconnects. Do you happen to be connecting to Rabbit through a load balancer?</div>
<div><br>
</div>
<div>We don’t have a create solution for this, but talked to several folks at the Summit for ideas.</div>

This has not been merged in yet, though.</div>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal">In our infrastructure we are observing that some compute nodes are reporting the state correctly but not consuming messages.</p>
<p class="MsoNormal">For the scheduler they are available, so it schedules VMs on them, and then the messages are pilling up in the compute.”host” queues.</p>
<p class="MsoNormal">Restarting nova-compute solves the problem. All old messages in the queue are consumed and they start behaving properly until next time…</p>
<p class="MsoNormal">I don’t get anything interesting from the logs.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We are using rabbit 3.2.4 clustered with mirror queues and Havana 2.
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Anyone observed the same symptoms?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">thanks,</p>
<p class="MsoNormal">Belmiro</p>
