Let's upgrade Erlang to the latest stable version - 21. Although 22 is released there are plenty of incompatibilities and regressions so let's not to hurry there. So I'd choose to upgrade to 21 as the next step. Upgrading to 21 gives us at least better IO which will be beneficial for RabbitMQ.
Addressed with erlang-21.3.8.3-1.el8ost.
