Thank you, our version of pdns is quite old (from repo) so I hope 
upgrading it is the solution. I will report back.

Yes, the first CHG_ADD has populated DHCID and correct forward and 
reverse entries. Thats why I ask, maybe I can ignore this error. I 
wasn't sure if setting override-*-update was too aggressive
