Carbon Black App Control (formerly Cb Protection)
Issue/Introduction
Small subset of devices maxed out at 100% CPU Usage
Initialization Percentage shows 0%
Disabling Agent causes CPU usage to drop
Environment
Cb Protection Agent: 8.0.0.2322 (Patch 4)
Microsoft Windows: All Supported Versions
Cause
The behavior is caused by delay in script processing. If a server or workstation runs a large number of scripts concurrently, it can be delayed causing a spike in CPU which doesn't reduce over time
Resolution
Upgrade to 8.0.0.2562 (Patch 6)
Additional Information
A temporary workaround is to disable script processing until the upgrade can take place
