Hi we use fortiweb 1000D some time cpu usage is higher then(80%) while we have a low traffic 1- what is the reason for this issue? 2- what is the critical value for cpu usage? 3- if cpu usage get to critical value what is possible events? 4- we set on configuration that store all event log in device disk and set threshold for cpu usage 60% some times we see o cpu usage is higher then 80% in GUI but in event log do not store. why?
