More useful to us is the rabbit logs and the rabbit-sasl logs. I suspect
you've run out of memory. This is a well known issue with the current
version of RabbitMQ and is caused by the fact that Rabbit always keeps
all messages in RAM.

This is being solved by the "new persister" which is frequently
mentioned on list. The "new persister" is currently towards the end of
its path through QA and is widely used by the community. It is however
still unreleased, and you have to compile from source. The new persister
allows Rabbit to push messages to disk and release them from RAM when it
starts to run out of RAM, thus solving the problem I suspect you're
suffering from.
