OpenClaw WhatsApp Issue: Health monitor race condition with Baileys 30-minute disconnections

Problem Summary

WhatsApp Web gateway experiences a race condition that causes ~7-hour outages:

1. Normal operation: WhatsApp server disconnects every ~30 minutes (status 499)
2. Baileys retry mechanism: Automatically attempts reconnection (Retry 1/12 in ~2s)
3. Health monitor: Also detects disconnection and restarts channel
4. Race condition: Both systems try to control the same channel simultaneously
5. Result: Channel enters shutdown state, Baileys retry stops, health monitor restart fails
6. Outcome: ~7-hour complete outage until manual gateway restart

Expected Behavior

• Baileys retry should continue until successful reconnection
• Health monitor should work independently without interfering with retries
• No manual intervention should be required for routine disconnections

Root Cause Analysis

Timing

• messageTimeoutMs: 1,800,000ms (30 minutes) - hardcoded default
• watchdogCheckMs: 60,000ms (1 minute) - hardcoded default
• WhatsApp server disconnect: ~30 minutes (variable timing)

Race Condition Details

1. minutesSinceLastMessage > 30 triggers watchdog restart
2. Baileys retry mechanism is also active simultaneously
3. Channel gets stuck in "channel stop exceeded 5000ms after abort" state
4. No further retries occur from either system

03:02:13 ⚠️ No messages received in 30m - restarting connection
03:02:54 [health-monitor] restarting (reason: disconnected)
03:02:59 channel stop exceeded 5000ms after abort; continuing shutdown
03:03:16 channel exited (408)
# Silence for 7 hours until manual restart
09:56:17 [gateway] ready

Proposed Solution

Phase 1: Configurable timeouts (Priority)

Add config keys to prevent hardcoding and allow adjustments:

channels:
  whatsapp:
    web:
      messageTimeoutMinutes: 35  # Higher than server disconnect timing
      watchdogCheckSeconds: 120  # Less frequent to avoid race condition

Phase 2: Coordination mechanism (Future enhancement)

Implement mutual exclusion or coordination between Baileys retry and health monitor.

Current Workaround

Manual gateway restart every ~7 hours (not sustainable).

Impact

• Critical for WhatsApp reliability
• Affects cron jobs (Ryan pep talk, portfolio briefs, etc.)
• Only affects isolated sessions (main sessions work)

Steps to Reproduce

1. Run OpenClaw WhatsApp gateway
2. Wait ~3-4 hours for race condition to occur
3. Observe complete disconnection lasting ~7 hours
4. Manual restart required
