I have the following settings in /etc/rabbitmq/rabbitmq.conf

RABBITMQ_NODE_IP_ADDRESS=127.0.0.1
RABBITMQ_LOG_BASE=/opt/logs/rabbitmq
RABBITMQ_MNESIA_BASE=/opt/otp/mnesia
RABBITMQ_PIDS_FILE=/opt/otp/pids

and in /etc/rabbitmq/rabbitmq_cluster.conf:

[rabbit at localhost].

"user" has read & write permissions to these directories.

I just did and with only one node everything is fine with both versions.

Sorry. Screwed versions. 1.5.3 returns both and 1.5.4 only one.

Following http://www.rabbitmq.com/clustering.html#single-machine I just
put "[rabbit at localhost]." into /etc/rabbitmq_cluster.conf
