Well I am unable to locate the error message as it does not appear to
be logged. In the interim I have done a lot more research and I now
suspect that I have two separate problems:

1. Since the yum update did not complete then it never had a chance
   to update the rpm database,

2. We probably have one or more packages that have been install but
   the predecessor has not be removed.

I have done the following:

a. Rebuilt the rpm database:

    rm -f /var/lib/rpm/__db*
    rpm --rebuilddb

b. I then retried the yum update this aborted report conflicts in
   systemtap packages.

c. I listed the installed systemtap packages:

   rpm -qa | grep systemtap | sort

   This revealed that there were two systemtap-devel packages
   installed and I removed the newer one.

d. I then retried yum update and this appeared to work fine until it
   got to:

   Cleanup  : 1:xorg-x11-drv-nouveau-1.0.1-3.el6.x86_64      286/513

At this point the system appears to be hung. I can not proceed any
further this evening as I am working on this from home and I do not
have physical access to the server to reboot it. In the morning I
will reboot the server and try again but this time I am going to do
a "yum clean all" to the rpm database rebuild.

Any thoughts or comments would be appreciated.

That's al for now.
