If you run RabbitMQ on RHEL9 family hosts (CentOS Stream 9, RockyLinux 
9, AlmaLinux 9) and you see 1.6GB memory use then consider limiting 
amount of file descriptors:

> EL9 (both CentOS Stream 9 and Rocky Linux 9) have 1073741816 while
 > CentOS Stream 8 has 1048576 - after lowering it's acceptable
 > memory usage.
