Jira issue: CRDB-66047

Start with util/startup.TestStartupFailureRandomRange and reproduce the release-26.2 failure using the linked invocation details. Read the referenced internal guide and inspect the goroutine stack, including pkg/rpc/auth.go:192 and pkg/util/stop/stopper.go:358; done means the intermittent failure is explained and the relevant test or startup behavior is verified across the reported branches.
