The ulimit settings for rabbitmq are set in /etc/default/rabbitmq-server. It can be easily proven that limits are applied:

root@node-1:~# pgrep -f -l rabbitmq
6738 rabbitmq-server
6756 su
6757 sh
6758 beam.smp
root@node-1:~# cat /proc/6738/limits | fgrep 'open files'
Max open files 102400 105472 files
root@node-1:~# cat /proc/6758/limits | fgrep 'open files'
Max open files 102400 105472 files
