Open Stack

Hello,

I installed OpenStack Juno; the issue I'm observing is that RabbitMQ
running on the controller (package rabbitmq-server-3.1.5-10 installed
by yum) is not stable, i.e. it quickly eats up the memory and shuts
down; controller has 2G of RAM. Below is the messages from logs and
'systemctl status' before the daemon died:

=INFO REPORT==== 18-Dec-2014::01:25:40 ===

=WARNING REPORT==== 18-Dec-2014::01:25:40 ===

I upgraded the daemon to version 3.4.2 taken from
http://www.rabbitmq.com/releases/rabbitmq-server/v3.4.2/rabbitmq-server-3.4.2-1.noarch.rpm
This didn't help either -- although the new daemon consumes memory
slower then 3.1.5, it does eventually shuts and closes.

I know about set_vm_memory_high_watermark, but it doesn't solve the
issue. I want to ensure that the daemon doesn't shut down abruptly. I
wonder if someone saw this before and could advise?
