For the archives.

After a lot of trial and error testing finally determined the cause of 
this problem is ddclient. When I disable ddclient from running those 
messages stop happening.

ddclient is a dynamic DNS auto updater written in perl. I have now 
deinstalled ddclient and written my own dynamic DNS auto updater sh 
script that I am calling dynip with intention to add it to the port 
system later.
