# 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:**
|
|
```python
|
|
# BEFORE (defective)
|
|
if __name__ == "__main__":
|
|
run_weather_job() # Runs once, then exits
|
|
```
|
|
|
|
## Corrective Action
|
|
|
|
Implemented persistent execution loop with exception handling:
|
|
|
|
```python
|
|
# 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
|
|
|
|
1. **Golden Dataset updated** — Added Runtime Longevity Test
|
|
2. **Burn-in requirements updated** — Continuous execution verification required
|
|
3. **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
|
|
|
|
- [x] Scheduler restarted with corrected code
|
|
- [x] New observations created within 1 minute
|
|
- [x] Reality Latency restored to <1 minute
|
|
- [x] Burn-in clock reset to require 72 hours of continuous operation
