downgraded the kernel to 2.6.9-5 ? (step-by-step)

[claven177]

On one of my cPanel/WHM servers I have a huge problem with PHP. Multiple times a day, the serverload is going to 45.00 / 50.00.

Some body told me downgraded the kernel to 2.6.9-5, all of problems maybe fixed.

But how to downgraded the kernel to 2.6.9-5 ? (step-by-step)

My Kernel current version: 2.6.9-22.EL

change /boot/grub.conf to

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hda7
# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu


default=1
which is the earlier kernel 2.6.9-5

and reboot yr server

or update your kernel to the latest 2.6.9-34 ?
