CPU usage increases suddenly after a few minutes

[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
0       total
[root@1087 ~]#

This is the list of /boot

Code:

[root@1087 boot]# ls
config-2.6.10-1.760_FC3         kernel.h-2.4.9
config-2.6.10-1.760_FC3smp      lost+found
config-2.6.5-1.358              System.map-2.6.10-1.760_FC3
config-2.6.5-1.358smp           System.map-2.6.10-1.760_FC3smp
grub                            System.map-2.6.5-1.358
initrd-2.6.10-1.760_FC3.img     System.map-2.6.5-1.358smp
initrd-2.6.10-1.760_FC3smp.img  vmlinuz-2.6.10-1.760_FC3
initrd-2.6.5-1.358.img          vmlinuz-2.6.10-1.760_FC3smp
initrd-2.6.5-1.358smp.img       vmlinuz-2.6.5-1.358
kernel.h                        vmlinuz-2.6.5-1.358smp
[root@1087 boot]#

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
