Chrome users are hitting Error Code 5 despite having ample system RAM. The issue stems from a hard limit in the V8 JavaScript engine, which caps memory usage at 4GB per tab on 64-bit systems.

Modern Single Page Applications like Figma and Linear can exhaust this quickly, especially with media-heavy tabs open. Chrome's built-in Memory Saver waits for system pressure before acting, often too late to prevent crashes.

A local solution called SuperchargeBrowser enforces active resource management. It uses enforced serialization and priority allocation to suspend background tabs, freeing up V8's memory space for active tasks without cloud syncing or data collection.
