**Issue Evaluation** Category: `bug` | Status: **Confirmed** The reported issue is valid. `RocketMQDLQProvider#buildDLQGroup` catches `examineTopicStats` failures and leaves the message count at zero, making the DLQ appear `EMPTY`. This is indistinguishable from a genuinely empty DLQ, hiding ACL, network, or broker failures from the control-plane UI. **Root Cause:** Exception in topic-stats query is swallowed; zero-count default masks the failure. **Impact:** Operators cannot distinguish "no dead letters" from "could not check dead letters", leading to false confidence in message processing health. **Severity:** medium The proposed approach — preserving empty DLQ as `EMPTY` while marking failed queries as unavailable — correctly separates the two states. *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
