**Issue Evaluation** Category: `bug` | Status: **Confirmed** This is a well-documented concurrency bug in the native alert collection mechanism. The issue is clear: **Root Cause:** The lease management in the alert collection process does not properly handle long-running empty passes. When the collection process takes longer than the lease duration without processing any alerts, the lease expires and can be acquired by another instance, leading to duplicate processing or lost alerts. **Impact:** In distributed deployments, this can cause: - Duplicate alert processing - Lost alerts during lease transitions - Inconsistent alert state across instances **Severity:** High - affects data integrity in distributed alert collection scenarios. **Suggested Fix:** Implement lease renewal mechanism that extends the lease before expiration, even during empty passes. Consider using a heartbeat pattern to keep the lease alive while the collection process is active. An automated fix proposal can be generated.
