Problem: Nlog RabbitMQ Opens too many connections under heavy load

[ahmetcanyilmaz]

I have a .NET MVC application installed on multiple servers behind a load balancer. RabbitMQ is installed on Centos8. While doing load testing, I saw that the Socket descriptors reached the maximum value and after a certain point, requests to RabbitMQ did not go. Servers opened too many connections. When I shut down one of the servers, I saw that the connection numbers of the other servers increased. The number of Connections per server reached 280.
How can we determine the server-based connection limit?
