Hi All On several occasions I have noticed that for no apparent reason the CPU is extremely busy. The system monitor shows "0%idle" even after I closed down all the running programs. I left it for a couple of hours (thinking its cleaning up something) but still busy. The only way to get rid of it is reboot comp Does anyone know what causes this or how to check what the comp is doing? Would it have to do with the kernel ? I'm using SuSE 8.1. TIA -- /bill from 169 west 19 south (where the hell is that?) Registered Linux user #298909 http://counter.li.org

Use the command line utilty `top'. It shows you a list of processes, sorted to CPU usage by default. You can also kill process from within top. See `man top' for further details. Paul.
Thanks. I just have to wait till it happens again and try it out. bill from 169 west 19 south (where the hell is that?) Registered Linux user #298909 http://counter.li.org On Saturday 08 February 2003 10:07, Paul Uiterlinden wrote:

For a long checks of CPU usage, you can use the package systat.It contains the following commands: iostat - Report Central Processing Unit (CPU) statistics and input/output statistics for devices and partitions. sar - Collect, report, or save system activity information. isag - Interactive System Activity Grapher Franz
Thanks for your reply. Cann't find systat on my system. Found System monitor, but this is a Gnome program there for help doesn't work. Have to wait until it happens again. /bill from 169 west 19 south (where the hell is that?) Registered Linux user #298909 http://counter.li.org On Saturday 08 February 2003 11:00, Franz Knuts wrote:

You could also just open an xterm and use top. A. Open Xterm B. type top C. shift + p (sorts by cpu usage) This will show you exactly what's using the most CPU. I believe top is one of the best multi-info tools out there..it's very useful. :) -- Ben Rosenberg ---===---===---===--- mailto:ben@whack.org Tell me what you believe.. I'll tell you what you should see.
I just did that and found a program called ""procinfo" is take up all my cpu usage. (between 96 and 99%). Do you or anybody else know what this ptogram does and if it is safe to ""kill"'. /bill from 169 west 19 south (where the hell is that?)

I'm sorry the name of package is sysstat (with double s). It's in Suse 8.0 These programs can monitor activity but don't say what processes are running. Franz

This happened to me twice: the (external) modem had crashed, and was making thousands of interrupts per second. It was solved by power-cycling the modem. You can check for that watching /proc/interrupts. -- Cheers, Carlos Robinson
