Developed a per-node STOMP connection limit for the rabbitmq-server repository, introducing the stomp.max_connections configuration to control resource usage under high connection churn. Leveraging Erlang for backend and network programming, the implementation validated configuration values to accept non-negative integers or infinity and enforced the limit within the STOMP connection handling layer. When the connection cap was reached, clients received a STOMP ERROR frame, improving system reliability and predictability. Comprehensive end-to-end tests were added to verify behavior, including edge cases such as a zero limit, and test hygiene was enhanced by resetting configuration after each run to maintain environment integrity.
