How to fix npm ERR! code SIGKILL npm ERR! errno SIGKILL npm ERR! process killed with SIGKILL in npm

# On Linux, check kernel logs
dmesg | grep -i 'out of memory\|killed process\|oom-kill'

# Or check syslog
grep -i 'oom-kill\|out of memory' /var/log/syslog

# In Docker, check container logs
docker logs <container-id> 2>&1 | grep -i killed

# docker-compose.yml
services:
  app:
    image: node:18
    mem_limit: 2g
    memswap_limit: 4g  # Total memory + swap

docker run -m 2g --memory-swap 4g node:18 npm install

# Create 2GB swap file
sudo dd if=/dev/zero of=/var/swap.1 bs=1M count=2048
sudo chmod 600 /var/swap.1
sudo mkswap /var/swap.1
sudo swapon /var/swap.1

# Deduplicate dependencies
npm dedupe

# Check for outdated packages
npm outdated
npm update

# Remove node_modules and reinstall cleanly
rm -rf node_modules package-lock.json
npm install

NODE_OPTIONS="--max-old-space-size=2048" npm run build

# WRONG - npm won't relay signals properly
CMD ["npm", "start"]

# CORRECT - node handles signals directly
CMD ["node", "server.js"]

# Monitor memory usage during npm install
watch -n 1 'ps aux | grep node | grep -v grep'

# For Docker builds, watch memory in real-time
docker stats <container-id>

# Add debug logging
node --trace-gc npm run build 2>&1 | tee build.log
