**Issue Evaluation** Category: `bug` | Status: **Confirmed** This is a valid race condition bug in the Consumer page diagnostic UI. **Root Cause:** `ConsumerPage.loadProgress` allows concurrent async requests for the same consumer group to update `progressByGroup` in completion order. When an older request completes after a newer one, it overwrites the fresher diagnostic result. **Impact:** - Health Diagnostics shows stale data after "Re-diagnose" operations - Users see incorrect `diffTotal` values - Affects UI correctness, not system stability **Severity:** Medium - Reproducible with clear steps - Deterministic with deferred Promises - No data loss or crash, but misleading diagnostic information **Suggested Fix:** Track request sequence numbers or use request cancellation to ensure only the latest response updates the UI state. Common patterns: 1. Add a request ID/counter and ignore responses with stale IDs 2. Cancel in-flight requests before starting new ones 3. Use AbortController for fetch requests This issue is ready for automated fix proposal generation. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
