Thanks for the comments.  If not defragging, then do you or anyone else 
have suggestions as to regular maintenance that should be run on CentOS 
servers, besides running regular updates?

I don't do updates very often either, I'm afraid of breaking something.  
How do you guys handle this?    I could run 'yum update' on the dev 
server, and just let everything update, and then see if the basics are 
still working ok.  But it may be easy to miss something.  Usually I just 
update apache/php/mysql and leave the rest alone.  Do you trust it 
enough to just do a full yum update every night from cron?
