🚨 Troubleshooting & Debugging

Common Issues and Solutions

1. Service Connection Issues

# Check service status
curl -f http://localhost:5000/health  # Base Server
curl -f http://localhost:5001/health  # LLM Server
curl -f http://localhost:5004/health  # Embedding Server
curl -f http://localhost:8080/v1/meta # Weaviate

# Restart services if needed
docker-compose -f "LLM server/weaviate/docker-config/docker-compose.yml" restart

2. Memory and Performance Issues

# Monitor GPU usage
nvidia-smi -l 1

# Monitor system resources
htop

# Check Docker container status
docker stats

# Optimize memory usage
export CUDA_VISIBLE_DEVICES=0,1  # Limit GPU usage
export OMP_NUM_THREADS=4         # Limit CPU threads

3. Model Loading Problems

# Verify Ollama models
ollama list
ollama pull llama3.1
ollama pull llama3.2:1b

# Check model files
ls ~/.ollama/models/

# Restart Ollama service
systemctl restart ollama  # Linux
brew services restart ollama  # macOS

4. Frontend Connection Issues

// Debug API connectivity
console.log('API Base URL:', CONFIG.baseUrl);

// Test API endpoint
fetch(`${CONFIG.baseUrl}/health`)
    .then(response => response.json())
    .then(data => console.log('API Status:', data))
    .catch(error => console.error('API Error:', error));
