Jira issue: CRDB-41979

Start with the roachtest README and the failure site at monitor.go:154, then inspect the logs and artifacts under /artifacts/restore/tpce/8TB/aws/nodes=10/cpus=8/run_1. Compare the related failures in #127634 and #126792 to determine whether this is the same recurring failure. Done means identifying the cause and validating a rerun of the restore test without the monitor failure.
