[rabbitmq-discuss] rabbitmq out of memory

Thu Jul 10 17:24:23 BST 2008

Hey,

We're having some memory problems with RabbitMQ and I'm trying to track
down their cause. What's happening is that RabbitMQ quite quickly starts to
eat up memory and around the 2GB mark dies (it's a 32bit machine). The logs
look fine and the startup.err just has a memory allocation error.

I've attached the output of stat_all() to see if that might help. It
doesn't look very informative. Is there another command I should be
running?

(specs)
redhat el5 32bit
erlang 12b3
rabbitmq 1.3.0

(stat_all)

RabbitMQ was using 1.7GB of RAM when I ran stat_all

Thanks,
