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

Alvin Voo Alvin Voo I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing. My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream. What I bring to your project: Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins. Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams. Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

Frequently Asked Questions

How do I check my bundle size?

Use npm run build with --analyze flag or use webpack-bundle-analyzer. Look for large dependencies

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
