I did a search online and found a way to make it start working, but I still experience the problem on some of my servers.
Below is the text I submitted for my open case that explains how I cleared the hangup, but this is not a fix. So I killed the yum session using kill The result is it left the process in the process list but stated it was "defunct". So I searched for a way to get rid of a defunct process and someone said I should try to kill the parent process. So I executed another ps -ef grep yum and got the parent process id.
Then I killed the parent process using kill You can watch the update log while the update is running. Managing automatic software updates in the web console.

These features also make it possible to use Yum to install nothing but security updates. To check for security-related updates available for your system, enter the following command as root :. Note that the above command runs in a non-interactive mode, so it can be used in scripts for automated checking whether there are any updates available.
The command returns an exit value of when there are any security updates available and 0 when there are not. On encountering an error, it returns 1. Analogously, use the following command to only install security-related updates:. Use the updateinfo subcommand to display or act upon information provided by repositories about available updates. The updateinfo subcommand itself accepts a number of commands, some of which pertain to security-related uses.
See Table 3. Table 3. Security-related commands usable with yum updateinfo Command Description advisory [ advisories ] Displays information about one or more advisories.
Replace advisories with an advisory number or numbers. Updating and Installing Packages. When updating software on a system, it is important to download the update from a trusted source. An attacker can easily rebuild a package with the same version number as the one that is supposed to fix the problem but with a different security exploit and release it on the Internet.
If this happens, using security measures, such as verifying files against the original RPM , does not detect the exploit. Thus, it is very important to only download RPMs from trusted sources, such as from Red Hat, and to check the package signatures to verify their integrity.
