Im getting the following error related to the management plugin, its
causing a nagios alert to fire, so I need to do something about it.
These are the versions Im running:
CentOS release 5.6 - 2.6.18-238.el5 (x86_64)
rabbitmq-management-plugins-2.2.0-2.noarch
rabbitmq-server-2.2.0-1.el5.noarch
erlang-kernel-R14B-02.1.el5.x86_64

It seems to have started happening every few hours over the past 30
hours or so, as far as I can see nothing has changed on the server in
question and rabbitmq is operating ok. Any help or guidance would be
appreciated,

    Hmm, not sure, and the mgmt guru is currently on holiday. All I can say
    for sure (without digging a lot further), is that an awful lot of
    improvements and bug fixes have been made to the mgmt plugin since
    2.2.0, and if it is an easy route for you to upgrade to the latest, you
    might find that the quickest path.

    Quick drive-by holiday posting: Yes, Matthew is right. This is a bug
    caused by the mgmt plugin looking up details for a queue which has since
    disappeared, so you're likely to see it when queues are churning. It was
    fixed in 2.3.0, but really you should upgrade to 2.6.0 :)

    Cheers, Simon
