**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
```typescript
private memoryOptimizationIntervalId: NodeJS.Timeout | null = null;
```
**Line 91:** ✅ Interval ID is stored when created
```typescript
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
```typescript
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.
