We have seen #6031, and none of the failed suites seem related to nsolid, but fastify flaky tests.

However, we are opening this issue to keep track of it and give updates. We'll monitor https://github.com/fastify/fastify/actions/workflows/ci-alternative-runtime.yml ,and if you see something wrong, please tag us as well.
