Expo. Confirmed fix, 2 June 2026.

Versions: eas update on a 3.7 GB RAM Linux box

Error:

```
exited with signal: SIGKILL ... Export failed
```

## Cause

The Metro export peaks during source-map serialisation. On a box with under 4 GB free the kernel OOM killer stops it regardless of --max-old-space-size.

## Fix

Publish one platform at a time with a heap that fits the box, or run the export on a machine with more memory:
```bash
NODE_OPTIONS=--max-old-space-size=6144 npx eas-cli update --channel production --platform ios
```
