100 % Cpu

Volcano · 10-01-2005, 05:03 AM

when i open my System Monitor GUI , i see

CPU used 100 % in the System monitor tab.

in the process monitor tab , i find no process to consume more CPU. why this happens ?

How can i recover from this ?
here is a result what i found when i run the top command in the shell.

Code:

why CPU used is shown to be 100% in the System Monitor GUI ?

i also in the process listing tab of the System Monitor no process is consuming much cpu except the gnome sustem monitor . it takes 6% only. then how top command is giving me such a big CPU usage statistics ? and how the System monitor GUI also shows CPU usage is 100 %.

everything here is a mistery .

Does all linux system consumes 100 % CPU usage . it is almost constant !!

i am on RED HAT 9

Volcano · 10-01-2005, 05:06 AM

do all of you get 100 % CPU in your System ? does it stay to be 100 % all he time. but ine is like this.

how dio i recover from this problem ?

Haiyadragon · 10-01-2005, 05:25 AM

Well, as you can see, webservd seems to be the bad guy. I don't know what it's for but killing it will fix the problem. Try "killall webservd", or if that doesn't work "killall -KILL webservd".

Linux systems most certainly don't use 100% cpu. Mine's at 10% average. X is using most of it.

Well the first 3 lines give 91.6+4.1+4.1 => 99.8 CPU%
Bit of rounding error, plus your session would make it mighty close to 100%. Gotta agree, webservd (presumably a webserver daemon) looks like the culprit.

Hi, ohh..yes, i remember the webservd NOW. its webserver Sun One i installed . You know, at the installation time, the webserver asked like this.....

Do you want the webserver to start when System Starts up ? Y/N

i blindly typed " Y".

Now, now as soon as i log on everytime the webserver gets started automatically !! ...i do not have to run the startup.bat file (of webserver ) even. i see, so, the webserver is taking a lot of CPU . right ?

will you please tell me how can i disable starting of webserver as soon as system starts up ? i want to start the webserver manually using startup.bat . i do the starting up of webserver manually ...do you think , it might take less CPU ? i dont know, but may be i could go for a try.

so question to you is :

How do i disable the auto-start of the webserver i installed ?

the name of the webserver is Sun One 6.1

what do i do now ?

Volcano · 10-02-2005, 10:59 PM

its NOT disabling

syg00 · 10-02-2005, 11:05 PM

Try (I'm guessing here);

Code:

/etc/rc.d/init.d/webservd stop

maybe try webserv as well if that doesn't do it.

bulliver · 10-02-2005, 11:06 PM

Well I guess you need to go through your scripts and find out what exactly is starting webservd.

Volcano · 10-02-2005, 11:06 PM

here is one more information i am sharing .
you know when i started my System , i got the mesages lots of "OK" and after some time xinetd started
and then i got a message my webserver ready to accept the request on port 80.

By the way,i want to disable it. the above command you provided did not work. please suggest me what should i do now ?

Volcano · 10-02-2005, 11:09 PM

/etc/rc.d/init.d/webservd stop

here is the result

# /etc/rc.d/init.d/webservd stop
bash: /etc/rc.d/init.d/webservd: No such file or directory
