ps -ef and ps aux 看到的daemon數量不一樣多

我用ps -ef 看到的數量與ps aux不一樣

去找了一下發現

ps aux 多了十幾個kproc,用ps -ef卻找不到半個kproc的daemon

請問這怎麼解釋

# ps aux |grep kproc

root 516 99.0 3.0 12 15964 - A Sep 02 45237:27 kproc

ps -ef and ps aux 看到的daemon數量不一樣多

Hi Joey,



The process "kproc" is the kernel's idle process that found on IBM AIX system and it means the system has 12 CPUs (kproc).



We don't see the process exist on Alpha Tru64 UNIX. Please collect more informations via the command "sys_check -all > check.html" if I'm wrong.



Best regards,

Richard.

you are right,this is a aix system

but not 12 CPUs

Hi Joey,



Please see the attachment .pdf.

And please contact with IBM for the detailed "kproc" infos.
