ashank : 08/03/04 08:14 PM : Incident created -   I've run this version of Mandrake on a couple of my boxes and have noticed, on both, that the CPU seems to be at 100% usage all the time, even when idling, no running programs, no open windows, etc.! This can't be normal. What could be hogging the CPU and how do I stop it? Could it be stuff running in the background, if so why would it be hogging all of the CPU!!?? Thanks in advance.
Linegod_7611 : 08/03/04 09:00 PM : Reply received -   What are you using to monitor the CPU? A 'kernel idle' process was added, and some programs misread this as a running process. At a console (ALT-F2 and type 'konsole') run 'top' and see what process is taking up the CPU. ------- Note: If this answer resolves your problem, please remember to close this incident.	Attachment

Linegod_7611 : 09/03/04 04:11 AM : Reply received -   It would appear that your CPU is 97% idle. Cpu(s): 0.0% user, 0.3% system, 0.0% nice, 99.7% idle What app where you using that was showing 100% usage? ------- Note: If this answer resolves your problem, please remember to close this incident.
ashank : 10/03/04 05:43 PM : More info provided -   Nothing. I just ran 1 of the system monitors that comes with Mandrake. Why would idle be at 99%?
Linegod_7611 : 10/03/04 07:29 PM : Reply received -   '99% idle' means that 99% of your CPU is _unused_. This is actually monitored by a process, and some old system monitors misinterpret this 'idle monitor process' as a true process, and report 'idle' as 'used'. Newer monitors (like those in 9.2 and 10 - ie gkrellm), will report this properly. -------- Note: If this answer resolves your problem, please remember to close this incident.	Attachment
