Why is Carbon Copy causing client pc CPU usage to spike?
This paper will give detailed instructions and background on how to resolve the CPU spike seen on clients running the Carbon Copy Solution caused by the client.exe process.
Altiris Carbon Copy provides a robust, quick, and clean interface to remote control a PC. Being combined into other Altiris solutions, it leverages the strengths and design of Help Desk Solution and Notification Server. Carbon Copy runs through a series of locally run services on the PC. These services are written to run with a small memory footprint to have the least affect on CPU resources. However, there exists a bug in which a particular Carbon Copy service can cause CPU spikes and/or high CPU utilization on the client PC.
Symptoms of this include but may not be limited to the following behaviors. Running the Task Manager on a Windows 2000 PC, a user may see multiple instances of the client.exe process being displayed. These may continue to multiply until the PC is in an unusable state. The client might also see a single client.exe process with an extremely high utilization, normally 90% or above without any active Carbon Copy connections being made. A third situation may be the user seeing a second client.exe process spawning every 5 to 10 seconds and spiking CPU resources during this interval.
Normal workarounds to these behaviors such as starting and stopping services, rebooting the client PC and reinstalling Carbon Copy have little effect on resolving these behaviors. Even if all these steps are taken, the behavior may return.
- Upgrade to the latest version of Carbon Copy Solution
- Enable the Carbon Copy Agent Upgrade policy
- Once all the Carbon Copy Agents have been upgraded, this symptom should no longer occur
