Can you explain what you are trying to achieve?

You get some control over how RabbitMQ responds to memory pressure with
the "vm_memory_high_watermark" configuration setting (see
http://www.rabbitmq.com/configure.html and

Memory for the broker is managed by the underlying Erlang VM. This
includes process heaps and separate space for message storage (Erlang
binaries). There are some internal flags that control Erlang memory
management, but it should not be necessary to touch them.
