Volgens Nagios nog steeds probleem met Dns, last check 21-12-2014 11.30 en deze state kent nagios al ruim 6 dagen.
Inet nu wel ok

named leek zonder problemen te draaien, maar toch: na herstarten van named is dns check wel ok.
Er is hier een lokale interface waar named blijkens /var/log/messages wel eens een probleem mee heeft.

Er lijkt ook nog een vuiltje in de config file te zitten bij sunny:
