[This test on roachdash](https://roachdash.crdb.dev/?filter=status:open%20t:.*TestCacheAutoRefresh.*&sort=title+created&display=lastcommented+project) | [Improve this report!](https://github.com/cockroachdb/cockroach/tree/master/pkg/cmd/bazci/githubpost/issues)

Start by reproducing sql/stats.TestCacheAutoRefresh with race detection using the linked invocation details, then inspect the reported call path beginning at pkg/kv/kvserver/replica_send.go:196 and the related store and node send functions. Done means the test no longer fails on the affected basalt branches, with the underlying failure explained and covered by the test run.
