✅ setInterval Resource Leak Bug - VERIFIED FIXED

Date: 2025-11-24
Status: ✅ ALREADY FIXED

---

🐛 Bug Description

The setInterval started in the AutonomousTaskEngine constructor was not stored and could not be cleared, causing a resource leak. Even after calling stop(), the interval continued running indefinitely.

✅ Verification

Location: apps/backend/src/mcp/cognitive/AutonomousTaskEngine.ts

Line 69: ✅ Property added to store interval ID

private memoryOptimizationIntervalId: NodeJS.Timeout | null = null;

Line 91: ✅ Interval ID is stored when created

this.memoryOptimizationIntervalId = setInterval(() => {
    this.queue.enqueue({
        type: 'memory_optimization',
        payload: { mode: 'nightly_consolidation' },
        baseScore: 80,
        isMaintenanceTask: true
    }, 80);
}, 1000 * 60 * 60 * 24);

Lines 128-133: ✅ Interval is cleared in stop() method

stop() {
    this.active = false;
    // Clear the memory optimization interval to prevent resource leak
    if (this.memoryOptimizationIntervalId !== null) {
        clearInterval(this.memoryOptimizationIntervalId);
        this.memoryOptimizationIntervalId = null;
    }
}

✅ Conclusion

Status: ✅ BUG IS ALREADY FIXED

The code correctly:

1. Stores the interval ID in a class property
2. Clears the interval when stop() is called
3. Prevents resource leaks

No further action needed for this bug.
