Recently we upgraded to 2020.3.4 and since then the controller is not sending jobs to the node. It will after we run the system setting, it will send the first set of jobs but after they complete the controller does not send any additional jobs and the queue backs up and jobs are only run on the controller. We have run the system settings a few different times and every time the node will get the initial set of jobs and then the controller will not send any new jobs once the first set of jobs is completed.
