PR #142660 introduced a bug where NodeGpuStatsResponse
uses writeVLong to serialize totalGpuMemoryInBytes,
which is -1 when no GPU is present. This causes
repeated WARN log flooding from OutboundHandler
on multi-node clusters with non-GPU nodes.

The bug was resolved in #142991 for 9.3.2.

Adds known issue docs with a mitigation (raising
OutboundHandler log level to ERROR).

ℹ️ Important: Docs version tagging

👋 Thanks for updating the docs! Just a friendly reminder that our docs are now cumulative. This means all 9.x versions are documented on the same page and published off of the main branch, instead of creating separate pages for each minor version.

We use applies_to tags to mark version-specific features and changes.

Expand for a quick overview

When to use applies_to tags:

✅ At the page level to indicate which products/deployments the content applies to (mandatory)
✅ When features change state (e.g. preview, ga) in a specific version
✅ When availability differs across deployments and environments

What NOT to do:

❌ Don't remove or replace information that applies to an older version
❌ Don't add new information that applies to a specific version without an applies_to tag
❌ Don't forget that applies_to tags can be used at the page, section, and inline level

🤔 Need help?

@mayya-sharipova @kilfoyle does this need to be backported ? Or are docs always served from main?

Thanks for checking @benwtrent! In the 9.x docs everything is served from main, so no need to backport.
