features:
- Two new variables (`rabbitmq_async_threads` and `rabbitmq_process_limit`)
have been added to the openstack-ansible-rabbitmq_server role.
The variable `rabbitmq_async_threads` limits the number of asynchronous
threads for file and socket I/O.
The variable `rabbitmq_process_limit` limits the overall number of supported
processes inside the erlang VM.
upgrade:
- The number of erlang asynchronous threads used by RabbitMQ have been
increased from the default of 32 to 128 in order to speed up message
processing.
- The maximum erlang process limit for RabbitMQ has been set to 1048576
in order to prevent virtual machine lockups which are caused when
this limit has been reached.
