No, there isn't a quick way to kill all jobs. You can kill all jobs by creating a SAS program that kills SAS processes (see link below for Unix server) or use O/S commands/scripts. Please be careful when doing this as you will be killing all jobs, including batch jobs that have been submitted to run overnight. If you decide to use a SAS program instead of O/S scripts, once you create and test your SAS program then you can deploy that job from within Management console and create a flow and schedule it to run every day.
