Why does the CPU shows more than 100% on any systems?
%CPU — CPU Usage : The percentage of your CPU that is being used by the process. By default, top displays this as a percentage of a single CPU. On multi-core systems, you can have percentages that are greater than 100%. For example, if 3 cores are at 60% use, top will show a CPU use of 180%.
How do you fix 100% CPU utilization bug when no processes are using CPU?
