Do you have any other application competeing to write to resolv.conf?
Do you have resolvconf(8) installed to manage this? I also maintain openresolv, 
which is a good resolvconf implementation.

The hook script to manage resolv.conf has hardly changed from 8.0.3 and there is 
nothing that stands out to say "this is the issue".
