Hi all,

I am running openstack Juno. Recently I have had severe problems with it, as rabbitmq fills the log with error messages like:

=ERROR REPORT==== 8-Mar-2016::11:17:16 ===
connection <0.8110.9>, channel 1 - soft error:
{amqp_error,not_found,
            "no exchange 'reply_bf8ddab13a254547974842e6a27f9099' in vhost '/'",
            'exchange.declare'}

=ERROR REPORT==== 8-Mar-2016::11:17:16 ===
connection <0.8122.9>, channel 1 - soft error:
{amqp_error,not_found,
            "no exchange 'reply_bf8ddab13a254547974842e6a27f9099' in vhost '/'",
            'exchange.declare'}

=ERROR REPORT==== 8-Mar-2016::11:17:16 ===
connection <0.8131.9>, channel 1 - soft error:
{amqp_error,not_found,
            "no exchange 'reply_bf8ddab13a254547974842e6a27f9099' in vhost '/'",
            'exchange.declare'}

and so forth. About 50MB of these get generated in about 5 minutes, then Rabbitmq just hangs and needs to be restarted. When I do the restart, my Openstack cluster actually works fine. Apparently something is wrong somewhere, but how do I find the broken component? Openstack logs do not reveal anything specific, just dropped MQ connections. 

nova-manage service list

shows everything up and running up to the point when rabbitmq dies.

Any ideas where to look? What is this "vhost '/'"?

I came across the similar issue as you, see --->

when execute 'heat stack-list' and by investigating the log of Heat api we saw the error message like below "Unexpected error occurred serving API: Timed out waiting for a reply to message ID 7daf49ca17cd4070bcfa1041890f84ae" ---->
