   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.
