This controls the number of channels allowed per single TCP connection.
RabbitMQ by default will negotiate a channel_max of 65535 (and in fact
AMQP won't allow more, it's an unsigned short).
But this is a very rare limit to run into. Are you running into a limit
on the number of *connections* you can open? This is affected by the
number of file descriptors available to the user running RabbitMQ - for
example, on a Debian based system you'll need to edit
