Might be related to these?  The fix for NM bug 739482 is included in 
NetworkManager-1.0.0-16.git20150121.b4ea599c.el7_1.x86_64, the current 
version on CentOS 7, but it might not be fully fixed?

It looks like that gets logged when the child "dhclient" process sends 
an event without a reason.  If that's the case, then switching from 
NetworkManager to the old "network" service probably won't help.  The 
problem is that "dhclient" is losing the address, and you'll be using 
that under the "network" service as well.
