up2date RPM package conflict error

When trying to run up2date, I get the following failure:

up2date -u

RPM package conflict error.  The message was:
Test install failed because of package conflicts:
package xerces-j-2.2.1-11 is already installed


Any suggestions on how I can fix this and why it is trying to install a 
package that it already has installed?

Thanks!
