So there's few things going on here. The primary issue is that RabbitMQ 
is running out of file descriptors due to too many connections being 
opened, and for various reasons the internal accounting that is supposed 
to prevent this from causing harm is getting out of sync with reality. 
There are already improvements that will be coming in the next release 
that will improve this situation and we have some ideas for how to fix 
it altogether.

But in the meantime you should look at increasing the number of file 
descriptors that are available to RabbitMQ.

Cheers, Simon
