CPU usage increases suddenly after a few minutes

assuming you are using the default kernel form FC, its probably so bloated you have a high lat kernel, mount your boot partition then do

Code:

du -ch /boot/<kernel>

replace <kernel> with the kernel you're running

Hi Cryotek,

Can you explane your post a bit more to me? Because it's running the latest kernel 2.6.10-1.760_FC3smp.

To Jolt,

Running manimod yes and hlstats,
2.6.10-1.760_FC3smp this is my kernel version

[cryotek]

heres an example for you.
as root mount your /boot partition. i.e.

Code:

mount /boot

then type in

Code:

du -ch /boot/2.6.10-1.760_FC3smp

[Delphis]

Code:

[root@1087 ~]# mount /boot
mount: /dev/sda1 already mounted or /boot busy
mount: according to mtab, /dev/sda1 is already mounted on /boot
[root@1087 ~]# du -ch /boot/2.6.10-1.760_FC3smp
du: cannot access `/boot/2.6.10-1.760_FC3smp': No such file or directory

[root@1087 ~]#

This is the list of /boot

Code:

[root@1087 boot]# ls

config-2.6.10-1.760_FC3smp      lost+found

Not sure what file i need.
Here is the grub.conf trying to start 1 cpu tonight

Code:

default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.6.10-1.760_FC3smp)
        root (hd0,0)
        kernel /vmlinuz-2.6.10-1.760_FC3smp ro root=LABEL=/1
        initrd /initrd-2.6.10-1.760_FC3smp.img
title Fedora Core (2.6.10-1.760_FC3)
        root (hd0,0)
        kernel /vmlinuz-2.6.10-1.760_FC3 ro root=LABEL=/1
        initrd /initrd-2.6.10-1.760_FC3.img
title Fedora Core (2.6.5-1.358smp)
        root (hd0,0)
        kernel /vmlinuz-2.6.5-1.358smp ro root=LABEL=/1

Did the following

Code:

[root@1087 /]# du -ch /boot/vmlinuz-2.6.10-1.760_FC3
1.5M    /boot/vmlinuz-2.6.10-1.760_FC3
1.5M    total
[root@1087 /]#

But can you explain me what this will do?

thnx delphis

[cryotek]

it'll just show the size of the kernel, smaller the kernel, less memory it'll take to hold.

[Delphis]

Code:

[root@1087 /]# du -ch /boot/vmlinuz-2.6.10-1.760_FC3smp
1.4M    /boot/vmlinuz-2.6.10-1.760_FC3smp
1.4M    total
[root@1087 /]# du -ch /boot/vmlinuz-2.6.5-1.358_FC3smp
du: cannot access `/boot/vmlinuz-2.6.5-1.358_FC3smp': No such file or directory

[root@1087 /]# du -ch /boot/vmlinuz-2.6.5-1.358smp

Here are the other kernels

Jolt,

Do you see any difference between Intel or AMD servers? Because what is see on the inet there is no prob with AMD servers.
