Bolt deployment

Build Fails - Memory Limit Exceeded or Process Killed

Deployment build fails with 'killed' status or 'out of memory' error. The build process gets terminated by the system before completing.

This happens when building large applications with many dependencies or heavy bundling requirements.

Error Messages You Might See

OOMKilled - killed due to out of memory FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed Build step failed - killed Error: JavaScript heap out of memory
OOMKilled - killed due to out of memoryFATAL ERROR: CALL_AND_RETRY_LAST Allocation failedBuild step failed - killedError: JavaScript heap out of memory

Common Causes

  1. Too many dependencies or unused packages inflating bundle
  2. Large assets (images, videos) not optimized
  3. Build process running inefficiently, using more RAM than needed
  4. Deployment platform has lower memory than required
  5. Global or unused npm modules not removed from node_modules

How to Fix It

Analyze bundle: npm run build -- --analyze to see what's taking space

Remove unused dependencies: npx depcheck

Optimize images: use Next.js Image component with loading='lazy'

For Vercel: upgrade to Pro for 3GB memory. For Netlify: use build plugins to optimize

Consider: npx nx affected:build for monorepos, or split large apps

What are common culprits for large bundles?

Heavy libraries like Lodash (use lodash-es), unoptimized images, unused icon packs

Can I increase memory in deployment?

Vercel Pro gives 3GB memory. For more, deploy elsewhere or reduce bundle size
