After upgrading to v13 of the Kace agent machines experienced an issue with scripts looping continuously. This resulted in high CPU usage.
This only affected scripts set to offline and scheduled to run on a specific day. If scheduled to run every day then not affected.
Quest developers are looking at the issue (ref K1A-4002). Currently affects all latest versions of Kace.
Workaround is to change scripts to online or schedule to run every day.
