I have a locally hosted mirror of SL 6.[234] to manage about 200 
systems.  I use a reposync and createrepo to keep them updated daily.  
So far I've been accomplishing my upgrades for minor releases using yum 
and haven't had any troubles.  But the systems that I've upgraded to 6.4 
are showing some strange yum behavior.

After the upgrade the system does not see any updates.  For instance on 
6.3 the autofs package is 5.0.5-55, 6.4 has 5.0.5-73.  Systems that I 
did a yum upgrade on will not see 5.0.5-73 as an available update.

What I've tried so far:

If I change yum to use the scientificlinux.org repos the updated package 
is seen with no problem.

I can install the new autofs package with a "yum localinstall 
<filename>" and that has no problems so it shouldn't a problem in the 
rpm itself unless there's a problem that effects createrepo but not 
installation of the rpm.

I've poked around in the primary.xml.gz file and it appears to be 
correct but I'm not sure that I'd spot a problem in there.

It seems to be some problem with the createrepo utility but I've had no 
luck finding any errors or warnings to indicate where the fault might be.

I'm going to try to find a spare system that I can do a clean install of 
6.4 and see what happens with that.

Does anyone have an idea of what could cause this?
