Operational Status - NG7 Live

Last Updated: 2026-03-25 05:35 UTC
Status: ✅ FULLY OPERATIONAL

---

Current State

Component	Status	Details
NG7 (Windows)	✅ LIVE	Writing directly to Hz over Tailscale
Hz Server	✅ HEALTHY	Receiving scans ~5s interval
Nautilus Trader	✅ RUNNING	Processing scans, 0 lag
Scan Bridge	✅ RUNNING	Legacy backup (unused)

---

Recent Changes

1. NG7 Direct Hz Write (Primary)

• Before: Arrow → SMB → Scan Bridge → Hz (~5-60s lag)
• After: NG7 → Hz direct (~67ms network + ~55ms processing)
• Result: 400-500x faster, real-time sync

2. Supervisord Migration

• Migrated nautilus_trader and scan_bridge from systemd to supervisord
• Config: /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf
• Status: supervisorctl -c ... status

3. Bug Fix: file_mtime

• Issue: Nautilus dedup failed (missing file_mtime field)
• Fix: Added NG7 compatibility fallback using timestamp
• Location: nautilus_event_trader.py line ~320

Test Results

Latency Benchmark

Network (Tailscale):  ~67ms  (52% of total)
Engine processing:    ~55ms  (42% of total)
Total end-to-end:     ~130ms
Sync quality:         0 lag (100% in-sync)

Scan Statistics (Current)

Hz latest scan:     #1803
Engine last scan:   #1803
Scans processed:    1674
Bar index:          1613
Capital:            $25,000
Posture:            APEX

Integrity Checks

• ✅ NG7 metadata present
• ✅ Eigenvalue tracking active
• ✅ Pricing data (50 symbols)
• ✅ Multi-window results
• ✅ Byte-for-byte Hz/disk congruence

Architecture

NG7 (Windows) ──Tailscale──→ Hz (Linux) ──→ Nautilus
         │                        │
         └────Disk (backup)───────┘

Bottleneck: Network RTT (~67ms) - physics limited, optimal.

---

Commands

# Status
supervisorctl -c /mnt/dolphinng5_predict/prod/supervisor/dolphin-supervisord.conf status

# Hz check
python3 -c "import hazelcast; c=HazelcastClient(cluster_name='dolphin',cluster_members=['localhost:5701']); print(json.loads(c.get_map('DOLPHIN_FEATURES').get('latest_eigen_scan').result()))"

# Logs
tail -50 /mnt/dolphinng5_predict/prod/supervisor/logs/nautilus_trader.log

---

Notes

• Network latency (~67ms) is the dominant factor - expected for EU→Sweden
• Engine processing (~55ms) is secondary
• 0 scan lag = optimal sync achieved
• MHS disabled to prevent restart loops

System Recovery - 2026-03-26 08:00 UTC

Issue: System extremely sluggish, terminal locked, load average 16.6+

Root Causes

Issue	Details
Zombie Process Storm	12,385 zombie timeout processes from Hazelcast healthcheck
Hung CIFS Mounts	DolphinNG6 shares (3 mounts) unresponsive from 100.119.158.61
Stuck Process	grep -ri scanning /mnt in D-state for 24+ hours
I/O Wait	38% wait time from blocked SMB operations

Actions Taken

1. Killed stuck processes:

   • grep -ri (PID 101907) - unlocked terminal
   • meta_health_daemon_v2.py (PID 224047) - D-state cleared
   • Stuck ls processes on CIFS mounts

2. Cleared zombie processes:

   • Killed Hazelcast parent (PID 2049)
   • Lazy unmounted 3 hung CIFS shares
   • Zombie count: 12,385 → 3

3. Fixed Hazelcast zombie leak:

   • Added init: true to docker-compose.yml
   • Recreated container with tini init system
   • Healthcheck timeout processes now properly reaped

Results

Metric	Before	After
Load Average	16.6+	2.72
Zombie Processes	12,385	3 (stable)
I/O Wait	38%	0%
Total Tasks	12,682	352
System Response	Timeout	<100ms

Docker Compose Fix

# /mnt/dolphinng5_predict/prod/docker-compose.yml
services:
  hazelcast:
    image: hazelcast/hazelcast:5.3
    init: true  # Added: enables proper zombie reaping
    # ... rest of config

Current Status

Component	Status	Notes
Hazelcast	✅ Healthy	Init: true, zombie reaping working
Hz Management Center	✅ Up 36h	Stable
Prefect Server	✅ Up 36h	Stable
CIFS Mounts	⚠️ Partial	Only DolphinNG5_Predict mounted
System Performance	✅ Normal	Responsive, low latency

CIFS Mount Status

# Currently mounted:
//100.119.158.61/DolphinNG5_Predict on /mnt/dolphinng5_predict

# Unmounted (server unresponsive):
//100.119.158.61/DolphinNG6
//100.119.158.61/DolphinNG6_Data
//100.119.158.61/DolphinNG6_Data_New
//100.119.158.61/Vids

Note: DolphinNG6 server at 100.119.158.61 is unresponsive for new mount attempts. DolphinNG5_Predict remains operational.
