Recovering from a CPU spike

==============================================================
Description:

In the course of operation, a system's host processor usage may spike to high levels. Before taking steps to resolve this, it is important to determine the cause. High CPU can be caused either by external factors (higher than usual signaling traffic volume being sent to the system) or an internal issue to the SBC.

This document explains the procedure to analyze and recover a Net-Net 3000 or 4000-series from high CPU utilization.

Check the process(es) consuming the CPU:

Determine the spiking process by typing the show proc cpu command on the system experiencing the spike. This command displays the highest consuming processes. You can see the current usage per process in the far-right column
