Jira issue: CRDB-68490

Start by reproducing sql/logictest.TestParallel from the linked TeamCity build and inspect its artifacts. Read the stack-trace entry points in pkg/kv/kvclient/rangefeed/rangefeed.go, pkg/sql/stats/automatic_stats.go, and pkg/rpc/stream_pool.go to identify why the test does not complete. Done means the failure is understood and the test passes on release-26.3.
