Answer 1

I am running RabbitMQ 3.6.3 on Ubuntu 16.04 and with those newer versions the answer given here (using ulimit in the rabbitmq-server file) no longer worked for me.

The solution for me was to configure the limits for systemd in this file

/etc/systemd/system/rabbitmq-server.service.d/override.conf

In that file, put this configuration

[Service] LimitNOFILE=32768

Where 32768 is the number of file handles you want to configure.

If you edit that file directly, you'll need to reload the systemd configuration with

sudo systemctl daemon-reload

But you can also use systemctl to edit the file, in which case it reloads the configuration automatically

sudo systemctl edit rabbitmq-server
