When the etl_driver.sas process runs every 10 minutes, you might notice that your system accumulates large files in the C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp\SAS Temporary File folder. 

The SAS^® Viya^® operations infrastructure runs batch jobs throughout the day. These jobs run via the ops-agent component. This component ends any batch jobs that take a very long time to process. Unfortunately, on a Microsoft Windows operating system, any batch SAS jobs that are ended in this way are not completely removed. Instead, the temporary Work libraries and files for the jobs are left on disk.

To work around this issue, run the Cleanwork utility frequently. It is ideal to run it every 2–3 minutes to ensure that any unneeded Work libraries are removed as quickly as possible.

See SAS Note 8786, “New SAS^® Cleanwork Utility available to clean SAS temporary WORK folders and files.”
