[SOLVED] Centos is got slow

windstory · 03-01-2011, 11:15 PM

My box is centos 5.5 x86, and it is got slow nowadays.
The "top" is as attached.

Please let me know how to fix this.

Thanks in advance.

Hi windstory,

The output of top you posted may actually provide a hint (though before I looked at it I had my doubts).

Gnome-panel is using 291 megs of memory. This is way too much, and almost 60% of what your system has. You may want to see what removing some applets will do, it may be something strange going on with one of them. Have you added any new applets to it lately?

Cheers,

Please understand I'm not expert of Linux, and this is thepicture of remote server.

I wonder if I close Gnom the remote server will shut down.

If you're not worried about the x-server (graphical interface) on the "physical" side of the machine shutting down, run

Code:

/etc/init.d/gdm stop

as root to shut down gnome. This should not cause any problems with remote SSH if that is what you're concerned with (unless CentOS does something weird I'm not aware of).

In any case, if you're not worried about the x-server, you can always kill gnome-panel.

However, keep in mind neither of these solutions tell you exactly what the problem is. If it fixes things, try starting gnome up again and see if the problem automagically disappears?

Code:

/etc/init.d/gdm start

It's rather difficult for me to imagine what the problem is without looking at things myself (I'm not even sure what to ask for). Perhaps someone else will have some better insight if this doesn't fix your problem.

Awatto/

About the command "/etc/init.d/gdm stop", it shows this message;

Quote:

There is not such file or directory.

And "gdm stop" or "/usr/sbin/gdm stop" also shows;

Quote:

GDM is already running, cancel!

Is there another way?

Awatto · 03-02-2011, 12:54 AM

Hmm, sorry, perhaps CentOS uses XDM?

try

Code:

/etc/init.d/xdm stop

If that still doesn't work, CentOS may even use the same system as Debian (I didn't think it did, but perhaps).. try

Code:

service gdm stop

windstory · 03-02-2011, 01:16 AM

Code:

/etc/init.d/xdm stop

The message is "There is not such file or directory. "

Code:

service gdm stop

the message is "GDM: unknown service."

So I tried "telinit 3", then I make a picture as attached, please see and give me your opinion.

gnome-panel is still running, and is now consuming even more memory. It is likely an applet you are using has a memory leak or something is just plain configured incorrectly.

Sorry the previous suggestions haven't worked and for the late replies (I'm at work right now so I'm a little delayed, checking in between operations).

Try just straight up killing the gnome-panel process.

Code:

kill 4499

This will cause some weird side effects on the graphical end (when you eventually do log into the physical box) but should at least stop the memory leak for now.

Thanks. It worked.
