The following order of events was possible: - An ILM policy update cleared `cachedSteps` - ILM retrieves the step definition for an index, this populates `cachedSteps` with the outdated policy - The updated policy is put in `lifecyclePolicyMap` Any subsequent cache retrievals will see the old step definition. By clearing `cachedSteps` _after_ we update `lifecyclePolicyMap`, we ensure eventual consistency between the policy and the cache. Fixes #118406
