Use the CLI to view a list of the most system-intensive processes. This may show processes that are consuming resources unusually. For example:

The above command generates a report of processes every 10 seconds. The report provides the process names, their process ID (pid), status, CPU usage, and memory usage.

The report continues to refresh and display in the CLI until you press q (quit).

Once you locate an offending PID, you can terminate it:

If the issue recurs, you can use log messages and/or packet capture to determine the source of the issue. However, remember that packet capture itself increases CPU usage.
