**Issue Evaluation** Category: `bug` | Status: **Confirmed** Each `RocketMQMessageListener` creates a `ClientImpl` with 2×CPU-core thread pools. With N listeners on a 12-core machine, this creates 24N threads — clearly excessive. **Root Cause:** No thread pool sharing between listener instances; each creates independent `ClientImpl`. **Impact:** Resource exhaustion with many listeners. On a 12-core machine with 30 listeners = ~720 threads. **Severity:** High This should be addressed by sharing a common `ClientImpl` or thread pool across listeners. --- *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
