[rabbitmq-discuss] Management plugin issues

Tue Jan 18 23:20:14 GMT 2011

I'm having a couple problems with the management plugin on
2.2.0/Erlang 13B/Ubuntu 10.04.

First, I have several independent rabbitmq clusters, but they all seem
to wind up reporting back to the same stats database.  I assume this
is some Erlang network service advertising feature, but I'd much
rather have each cluster use its own separate stats db.  How can I
force that?

Second, it keeps dying.  That is, the nodes are running, but the
statistics database goes down, and I have to restart the node that
contains it to get the management API back.  I'm seeing messages like
this in the log:

Can anyone advise as to next steps in troubleshooting?
