This comprehensive fix addresses memory leaks in both backend and frontend that could cause server crashes after extended use. Backend fixes: - MemoryManager class monitors process and GPU memory usage - Automatic cleanup when thresholds exceeded (4GB process, 2GB GPU) - Whisper model reloading to clear GPU memory fragmentation - Aggressive temporary file cleanup based on age - Context manager for audio processing with guaranteed cleanup - Integration with session manager for resource tracking - Background monitoring thread runs every 30 seconds Frontend fixes: - MemoryManager singleton tracks all browser resources - SafeMediaRecorder wrapper ensures stream cleanup - AudioBlobHandler manages blob lifecycle and object URLs - Automatic cleanup of closed AudioContexts - Proper MediaStream track stopping - Periodic cleanup of orphaned resources - Cleanup on page unload Admin features: - GET /admin/memory - View memory statistics - POST /admin/memory/cleanup - Trigger manual cleanup - Real-time metrics including GPU usage and temp files - Model reload tracking Key improvements: - AudioContext properly closed after use - Object URLs revoked after use - MediaRecorder streams properly stopped - Audio chunks cleared after processing - GPU cache cleared after each transcription - Temp files tracked and cleaned aggressively This prevents the gradual memory increase that could lead to out-of-memory errors or performance degradation after hours of use. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> |
