What might be the reason? And how to fix?
Don't know reasons, but I have used a big hammer
to fix things like this:
Create the resolv.conf file the way you want it
to be, then do:
chattr +i /etc/resolv.conf
Thus making the file immutable and bypassing
all the helpful stuff that tries to change it :-).
