some time ago I noticed that some resolvers tend to sort IP Adresses in
numeric order, thus sending most of traffic to numerically smaller IP.
(iirc using nss_lwres caused this). 

However as others have noted, having multiple DNS records is NOT load
balancing and should not be used as such. you should better get/configure
load balancer like alteon, cisco ACE or linux ipvs. 

This should work much better, with less IP addreses and no requests to IP
that is currently down (health checks take care of that).
