The Memory Load sensor has detected a high memory load. This may cause excessive "swapping" of data between physical memory (RAM) and the virtual memory in the swap file on the hard disk. This can degrade computer performance.
To lower the memory load, close any non-essential applications.
If the Swap File Size and Utilization sensors show a small, highly utilized swap file, and the Disk Space sensor shows little free disk space, make some room on the hard disk. This will allow Windows to increase the size of the swap file.
Consider installing more RAM in your computer.
The trigger level for this sensor's alarm determines what Norton System Doctor considers a "high" memory load. To change the trigger level, click Change Alarm Settings.
