**Issue Evaluation** Category: `bug` / `enhancement` | Status: **Confirmed** **Analysis:** Each `RocketMQMessageListener` creates a `ClientImpl` that initializes a thread pool with `2 * CPU_cores` threads. With 30 listeners on a 12-core CPU, this creates ~720 threads, which is excessive and can lead to: - High memory consumption - Context switching overhead - Potential thread exhaustion under load **Suggested fix:** - Share a common `ClientManager` or thread pool across multiple listeners - Make the thread pool size configurable per listener or globally - Consider lazy initialization of thread pools **Workaround:** Reduce the number of listeners or use a shared client instance. --- *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
