+dont asume is that do all this checks you mentioned   1. FFmpeg processes not being properly terminated - This is a common cause of memory leaks in video streaming
+    2. Multiple FFmpeg instances running simultaneously - If the stop/start process doesn't properly kill previous instances
+    3. Celery workers accumulating memory - If video analysis tasks are not properly cleaning up
+    4. Video frames not being released from memory - In the analysis engine
+    5. WebSocket connections not being properly closed
+

+● FOUND THE SMOKING GUN! 🔥
+
+  Look at the Celery logo worker:
+  - PID 39: Using 17.5% memory (2.8GB) and 23.7% CPU
+  - PID 24: Using 8.0% memory (1.3GB)
+
+  That's a massive memory leak in the Celery logo detection worker! The workers are accumulating memory and not releasing it.
+
+  Let me check the celery-default worker too:

+
+● Perfect! This confirms it's specifically the logo detection Celery worker causing the memory leak. The default worker is using normal ~70MB per process, but the logo worker is consuming 2.8GB and growing.
+
+  Let me check what's in the analysis engine that's not being released:
+
+● Read(backend/ai_processing/analysis_engine.py)
+  ⎿  Read 50 lines (ctrl+r to expand)
+
+● The analysis engine holds these detectors as instance variables. Let me check the logo detection adapter that's likely holding onto model memory:
+
+● Read(backend/ai_processing/adapters/logo_detection.py)
+  ⎿  Read 80 lines (ctrl+r to expand)
+
+● FOUND IT! 🎯
+
+  The CLIPLogoDetectionAdapter loads the CLIP model in _load_model() at lines 65-69, but never unloads it. Every time the Celery worker processes a video segment:
+
+  1. Creates a new AnalysisEngine instance
+  2. Which creates a new CLIPLogoDetectionAdapter
+  3. Which loads the CLIP model into memory (~500MB+)
+  4. Never releases the model after processing
+
+  Since the Celery worker is persistent, each task accumulates more model instances in memory. That's why we see 2.8GB+ memory usage!
+
+  The fix is to either:
+  1. Make the model singleton/shared across tasks
+  2. Explicitly clean up the model after each task
+  3. Use worker max tasks to restart workers periodically
+
+  Let me check the rest of the CLIP adapter to see the complete picture:
+
+● Read(backend/ai_processing/adapters/logo_detection.py)
+  ⎿  Read 52 lines (ctrl+r to expand)
+
+● Perfect! I can see the complete problem. The CLIPLogoDetectionAdapter:
+
+  1. Lines 67-69: Loads heavy CLIP model and processor into memory
+  2. Lines 94-99: Runs inference with torch tensors
+  3. No cleanup method - never releases the model, processor, or GPU memory
+
+  Solution: Add proper cleanup and memory management
+
+  Let me implement the fix by adding cleanup methods and ensuring models are released after each task:
+

+● Now I need to add a cleanup method to properly release the model and add task-level cleanup. Let me add the cleanup method:
+
+
+> why it happened only on webcam?
+
+● Great question! The memory leak affected all logo detection tasks, but it was only noticeable with webcam because of the frequency difference:
+
+  Frequency Analysis 📊
+
+  Webcam Stream:
+  - Continuous 30fps video → HLS segments every ~2-6 seconds
+  - Each .ts segment triggers logo detection task
+  - With webcam running: ~10-30 logo detection tasks per minute
+  - Memory accumulation: 500MB × 30 tasks/min = 15GB/hour
+
+  RTMP Stream:
+  - Only runs when you manually stream from OBS
+  - You probably tested RTMP for shorter periods
+  - Intermittent usage = fewer tasks = slower memory accumulation
+  - Memory leak was still happening, just not reaching critical levels
+
+  Why Webcam Exposed It
+
+  1. Always-on nature: Webcam starts automatically and runs continuously
+  2. High segment frequency: More .ts files = more Celery tasks = faster leak
+  3. Sustained load: No breaks between segments like manual RTMP testing
+  4. System saturation: 2.8GB+ per worker × multiple workers = system choking
+
+  The Real Pattern
+
+  RTMP: Task → 500MB leak → (gap) → Task → 500MB leak → (gap)
+  Webcam: Task → Task → Task → Task → Task → 15GB accumulated → 💥
+
+  RTMP seemed fine because:
+  - You'd stream for 30 seconds, test, then stop
+  - Memory never reached critical mass
+  - System had time to recover between sessions
+
+  Webcam revealed the truth because:
+  - Continuous operation exposed the cumulative effect
+  - No recovery time between tasks
+  - Memory leak compounded until system became unresponsive
+
+  The fix I implemented (tensor cleanup, model release, garbage collection) benefits both RTMP and webcam - you just noticed it with webcam because that's where the leak reached critical mass first!
