Error Code 5 (Out of Memory) is the most frustrating error in Chrome. It often happens on machines with 32GB or 64GB of RAM, leaving users confused.
The reality? It has nothing to do with your total system RAM. It’s a hard-coded limitation of the V8 JavaScript engine.
The V8 Memory Ceiling
Chrome's V8 engine has a hard memory limit per renderer process. On 64-bit systems, this is typically 4GB per tab.
Modern Single Page Applications (SPAs) like Framer, Figma, or Linear can breach this limit in hours if they are left open alongside media-heavy tabs (YouTube/Twitter). Once that 4GB ceiling is hit, the process is killed instantly, resulting in Error Code 5.
Why Chrome's "Memory Saver" Fails
Chrome's built-in Memory Saver is too conservative for power users:
- Passive Logic: It waits for "system pressure" before acting, which is often too late for an unstable SPA.
- Zero Visibility: You can’t see which tabs are "at-risk" or force a suspension before a crash happens.
The Local-First Fix: Resource Governing
To prevent Error Code 5, you must move from passive saving to active governing.
1. Enforced Serialization
By enforcing a strict suspension policy (e.g., 10-minute idle), you serialize the state of background tabs and remove them from the active V8 process. This keeps the total "Commit Charge" low.
2. Priority Allocation
Ensuring background tabs are fully discarded (chrome.tabs.discard) ensures that your active foreground task has the full 4GB V8 limit available without fighting for address space.
