Jira issue: CRDB-65931

Start with the roachtest artifacts and logs linked in the report, then read pkg/cmd/roachtest/cluster.go around Start and clusterversion/setting.go around the reported fatal entry. Reproduce the tpccbench/nodes=3/cpu=4/mt-shared-process configuration and trace why SQL is not ready; done means identifying and addressing the startup failure, then confirming the test passes.
