## I'm hitting a `timeout` / `kernel-out-of-memory` limit with a `pnpm`/`yarn` project

If you're seeing that your jobs are regularly hitting a `timeout` / `kernel-out-of-memory`, this might be due to a package manager trying to update a large set of dependencies.

On Mend-hosted apps, it is recommended to use the repo-level configuration, [`toolSettings.nodeMaxMemory`](https://docs.renovatebot.com/configuration-options/#toolsettingsnodemaxmemory), to tune the maximum memory available for the `pnpm`/`yarn` commands to use this.

Mend-hosted apps don't set a maximum allowed `nodeMaxMemory`, so you can use [the upper limit of memory from your plan](./overview.md) as the maximum limit.

It is recommended to set this between 1.5GB and 2.5GB but may require tweaking according to your repository.
