According to BF-28143, the amount of time that this workload takes to run in suites with chunk migration and/or stepdown/kill/terminate ranges from about 2 minutes to more than 10 minutes. This large variance has made EVG unable to accurately predict the time it should give to each task and this has led to a lot of task-time-out errors in these suites on EVG. This issue will be investigated in SERVER-75532. For now, the workload should be disabled in these suites.
