[CentOS] yum clean all

There seems to be a lot of this needed lately.
I suspect the issue is 5.2 -> 5.3 transition.

Putting something like this in /etc/cron.daily/
when near a major update *might* make the transition times between point 
releases easier -

#!/bin/bash

RANGE=120
number=$RANDOM
let "number %= $RANGE"
delay=`/usr/bin/expr $number \* 60`
sleep $delay
/usr/bin/yum clean all > /dev/null 2>&1
/usr/bin/yum makecache > /dev/null 2>&1

-=-
Point of the random delay is to not have lots of people hit all the 
servers at once.
