Jira issue: CRDB-68409

Start with the roachtest artifacts and logs linked in the report, then inspect pkg/cmd/roachtest and the failure at cluster.go:4230. Trace the MANIFEST flush error reported at pkg/pebble/version_set.go:456 and compare the run with the roachtest README. Done means the ycsb/E/nodes=3 basalt configuration completes without the unsupported protocol version failure.
