Think this is an issue on the litmus side. We probably need to update to newer versions of litmus. Think we currently are using 1.* version and they are on 3.
We are also working on taking out litmus references and add in our own, in house, versions of tests similar to this. https://github.com/redhat-chaos/krkn/blob/main/docs/arcaflow_scenarios.md#sysbench-cpu-hog
