Incident Report: LIFE-INC-0001
Summary
| Field | Value |
|---|---|
| Incident ID | LIFE-INC-0001 |
| Title | Scheduler terminated after first execution |
| Severity | High |
| Status | Resolved |
| Detected | 2026-07-05 02:49 UTC — Burn-in monitoring |
| Resolved | 2026-07-05 02:50 UTC |
Impact
- Reality Latency: Increased from target (<60 min) to 661 minutes (~11 hours)
- Data Freshness: Stale — no new observations created
- Coverage: 181 roads affected
- User Impact: None (system not yet customer-facing)
Root Cause
The scheduler executed one iteration of the weather pipeline and then exited. The original implementation lacked a persistent execution loop. It performed a single run and terminated successfully, giving the appearance of correct behavior during manual testing.
Code defect:
# BEFORE (defective)
if __name__ == "__main__":
run_weather_job() # Runs once, then exits
Corrective Action
Implemented persistent execution loop with exception handling:
# AFTER (corrected)
if __name__ == "__main__":
run_weather_job() # Run immediately
while True:
time.sleep(3600) # Wait 1 hour
try:
run_weather_job()
except Exception as e:
logger.error(f"Scheduler error: {e}")
time.sleep(300) # Retry after 5 minutes
Preventive Actions
- Golden Dataset updated — Added Runtime Longevity Test
- Burn-in requirements updated — Continuous execution verification required
- Monitoring enhanced — Alert if no observations created within 2 hours
Lessons Learned
"A system is not production-ready because it runs once. It is production-ready because it continues to run correctly over time."
- Manual testing of a single execution is insufficient for scheduled jobs
- Burn-in periods must verify sustained operation, not just correctness
- Monitoring must detect absence of expected activity, not just errors
Verification
- Scheduler restarted with corrected code
- New observations created within 1 minute
- Reality Latency restored to <1 minute
- Burn-in clock reset to require 72 hours of continuous operation
