killall -9 rpm; killall -9 rpmq; killall -9 yum; killall -9 upcp

rpm –rebuilddb (to rebuild your cPanel/Yum DB)
yum –exclude=kernel* -y update
yum clean all

Requirements for RoR
There are a few major requirements for installing Ruby on Rails (http://rubyonrails.org/) on a cPanel server. First, cPanel 11 must be running on the server. This can be verified by checking at the version number in the upper right-hand corner of WHM.
Installing Ruby on Rails in cPanel does require some command line interaction, so you will need to make sure that you can log into your server via SSH as root. Furthermore, cPanel requires that your server contain a working yum configuration. You can check this before trying to install Ruby by running yum list ruby from SSH, if it works without error, you should be fine.

AMD Opteron
AMD is putting the spotlight on its upcoming six-core 45-nanometer AMD Opteron processor, code-named Istanbul, with live demonstrations on YouTube. The x86 six-core processor is designed for systems with two and four or more sockets, and is due in the second half of this year.
Istanbul is compatible with current AMD Opteron processor-based systems, and to prove this, Advanced Micro Devices Inc. demonstrated on YouTube a live upgrade of a system based on 45-nm quad-core AMD Opteron processors to the six-core Istanbul processors. According to the time-lapsed video, the upgrade took more than eight minutes.
AMD claims Istanbul provides better performance and efficiency than other Opteron chips, and a simple performance demonstration on YouTube shows four Istanbul processors operating and running virtual machines.

Please ensure to read the following message carefully as there is important information about MySQL and Automated process killers in relation to the cPanel 11.24 upgrade.
MySQL Root Password
———————————
With cPanel 11.24 now available, it is imperative to ensure that you have set your MySQL root password before upgrading to the latest version of cPanel. If you have previously skipped this step, you can set it now using the “MySQL Root Password” function in WebHost Manager. Failure to set a MySQL root password may cause database corruption on systems running MySQL 4.1 with InnoDB tables. Please set your MySQL root password as soon as possible to avoid any issues. Machines without a MySQL root password set allow access to any database by any user so it is imperative that a password is set as soon as possible.
If you have moved /root
——————————
If you have set root’s home directory to something other than /root, you will need to copy .my.cnf from root’s home directory to /root/my.cnf. In the future, this process will be automated.
Automated process killers
————————————
If you have a system in place that automatically kills processes taking up a lot of CPU time, you should disable them before running the cPanel update as the size of the update has triggered many of these systems. These process killers will kill updates or related process in the middle of the process and cause issues. If you have a failed update, you can force a re-update by running /scripts/upcp –force
