OK ... yum caches metadata ... so for a period of time there is a file
in cache that MIGHT be different (if there are changes on the mirror).

You should start with this if you have that problem:

yum clean metadata

However ... this sounds like a different problem because ...
yumgroups.xml never really changes, except when we release a new ISO.

Are you rebuilding your metadata with createrepo ... if you are, are you
using the -g option?
