....which reminds me.  I haven't delved into the 64-bit CentOS on 
production machines yet.  Are there any glaring potential gotchas for 
generic LAMP type usage?  They won't be doing anything exotic...just 
serving up web content and perhaps replace some dedicated DNS/bind and 
mail/postfix boxes.  All the old systems being replaced are currently 
running CentOS 3.7 and I'd like to start migrating everything to 64-bit 4.3.

Cheers,
