we change /etc/security/limits.conf (actually add an entry to
/etc/security/limits.conf.d) for the rabbit user.
We just do that for the non-compute nodes.

There is just one queue that is building up: notifications.info - there are no
consumers for it.
I have upped the ulimit for the rabbitmq server (by changing
/etc/default/rabbitmq-server) but that hasn't made any difference.
Are you also upping the limits on the compute nodes?
cheers

Delete issues in my experience are typically linked to messaging getting stuck

RMQ queue lengths and see if any are building up.
Have you adjusted your open file descriptor limits ? The default Linux limit
(1024) is NOT enough in our experience for any reasonable
sized system. We've seen that cause messaging outages.

Did you ever come to the bottom of this?
We are seeing the same thing with a brand new Icehouse / Ceph installation
(using the stock distributions)
Restarting nova-compute on the compute nodes usually makes the instances go
away (or resetting the state, and then restarting nova-compute)
We see this problem intermittent but frequent enough to be really annoying.
The log files have so far not shown anything conclusive: I got an "Unknown auth
strategy" error, but according to
https://bugs.launchpad.net/python-neutronclient/+bug/1297309 this is a red
herring.
Anyone else running into this problem or having solved it?
cheers

Hi,
I just finished my upgrade to icehouse, everything works just fine but... i
can't delete my instances!
When i delete instance (from cli or from horizon) :
* The VM goes to "deleting"state
* Vm are destroy from KVM
* But nova list & horizon continue to display the "deleting" state
Some time after, the Vm state goes to "ERROR" and in nova-compute.log i can see
: "Unauthorized: Unknown auth strategy\n" (from neutronclient)
Any idea?
Thx!
