+h2. arv:WorkflowRunnerResources
+
+Specify resource requirements for the workflow runner process (arvados-cwl-runner) that manages a workflow run.  Must be applied to the top level workflow.  Will also be set implicitly when using @--submit-runner-ram@ on the command line along with @--create-workflow@ or @--update-workflow@.  Use this to adjust the runner's allocation if the workflow runner is getting "out of memory" exceptions or being killed by the out-of-memory (OOM) killer.
