[rabbitmq-discuss] Irregular service failure

Wed Aug 8 10:58:01 BST 2012

Hi, 

I have exactly the same situation. Although the message volumes are 
slightly less probably 10,000 msg/day.. I am currently running on RabbitMQ 
2.8.4. I have tried looking in the logs and I cannot see anything strange. 
Any other ideas?

Thanks Colin
