I have another one here on Windows 2016 that seems to result from an OOM. https://buildkite.com/elastic/elasticsearch-periodic-platform-support/builds/2768#018f831a-412e-43ef-a692-004c4db0417c

I'm looking at several "7.17 and windows-2016" and just want to link another issue I've just observed here: https://github.com/elastic/elasticsearch/issues/108755

Setting to medium risk since this is only on windows2016.

low-risk, just a test bug I think
