I cannot help with why its happening, but I can help with a solution.

Now days, regardless of whether 'network' or NetworkManager are in 
control, if you want your /etc/resolv.conf to be specific, then set up 
your primary interface definition to make it so.

In the file: /etc/sysconfig/network-scripts/ifcfg-<iface>

You need to add all of your specific resolv.conf entries, such as:

DNS1="216.239.32.10"
DNS2="216.83.130.2"
DNS3="216.83.130.7"
DOMAIN="mydomain.com"
SEARCH="mydomain.com. yourdomain.com. otherdomain.com."

Good Luck!
