Symantec Endpoint Protection server exceeded maximum requirements

I got this alert message from the server.

Message from:
      Server name: Servername
      Server IP: 10.102.200.100
 
Server ServerName health status: poor.
Reason: CPU usage on your Symantec Endpoint Protection server exceeded maximum requirements.
Status reported on 2010-03-29 18:45:21.
 
First notification of the current failure condition occurred on 2010-08-29 09:55:30.


But I checked on the CPU usage:

Server Information

Status Details

Server Name Status Health Status Reason CPU Usage Memory Usage Free Disk Space MyServerName Online Poor Server has less than 500 MB of free disk space. 11% 33% 433 MB

As you can see, the CPU usage indicated in the report is clearly NOT the issue. 

But when I checked the drive C: disk space, it was true that the free space is less than 500MB.

I tried to run the disk clean up, to add more space. then I got 2GB. The issue resolved.

This is a bug alert from Symantec Endpoint Protection.
