When cacheComponents is enabled, the export worker serializes the entire batch of static pages' resume data caches into a single IPC message, exceeding Node's maximum string length. process.send throws RangeError: Invalid string length, which becomes an unhandledRejection, leaving the parent waiting indefinitely and causing the build to hang at 'Generating static pages'.
Since Next.js 16.3.0, the published .d.ts files reference global type names URLPatternInput, URLPatternOptions, and URLPattern generic parameters that are only available in TypeScript 6.0+. This causes TypeScript 5.x users with skipLibCheck: false to encounter TS2304 errors in next/dist/server/web/spec-extension/url-pattern.d.ts, breaking typechecking for any project that types its next.config.ts.
In Next.js 16.3.6 and 16.3.8, a render error during an in-flight server action causes the shell to suspend repeatedly, eventually throwing minified React error #482 and replacing the page with 'This page couldn't load' instead of rendering error.js.
