    HI,

    Could you please check out the logs ?

    It may be due to the kernel problem or the insufficient Ram?

    Paste the log as well as the free -m

    Awaiting your reply,

    Hi,

    I can see some kernel warnings!!

    I would suggest you to go the kernel upgradation, Before that please ensure whether the server is booted up with the correct kernel.

    /etc/grub.conf

    There are problems like this when there is an error in the openvz installation.

    Please go for the kernel fix and it should be okay.

    Pray to god before you keep your hands on the server

    Thanks and regards,
    Tam007

    is this correct:

    # grub.conf generated by anaconda
    #
    # Note that you do not have to rerun grub after making changes to this file
    # NOTICE: You do not have a /boot partition. This means that
    # all kernel and initrd paths are relative to /, eg.
    # root (hd1,0)
    # kernel /boot/vmlinuz-version ro root=/dev/md2
    # initrd /boot/initrd-version.img
    #boot=/dev/md2
    default=0
    timeout=3
    splashimage=(hd1,0)/boot/grub/splash.xpm.gz
    hiddenmenu
    title openvz (2.6.18-194.26.1.el5.028stab079.2)
    root (hd1,0)
    kernel /boot/vmlinuz-2.6.18-194.26.1.el5.028stab079.2 ro root=/dev/md2
    initrd /boot/initrd-2.6.18-194.26.1.el5.028stab079.2.img
    title CentOS (2.6.18-194.el5PAE)
    root (hd1,0)
    kernel /boot/vmlinuz-2.6.18-194.el5PAE ro root=/dev/md2
    initrd /boot/initrd-2.6.18-194.el5PAE.img
