## 12. Known Issues & Limitations
### Current Limitations
1. **Disk Space**: Server at 98% capacity (184GB used of 197GB)
- **Action Required**: Clean up old files or expand disk
- **Impact**: May affect backup retention
- **Priority**: HIGH
2. **Single Instance**: Running in fork mode (not cluster mode)
- No load distribution across CPU cores
- Consider cluster mode for high traffic
3. **No External Monitoring**: Relies on local health checks
- Consider external uptime monitoring service
- Would detect network-level issues
### Resolved Issues
- Health endpoints implemented ✓
- Auto-restart capability working ✓
- Backup system operational ✓
- Deployment automation complete ✓
