[7.075] DNS-Proxy errors [NOTABUG]

Hi,

since days I see every 15 Minutes an errors in the DNS Proxy logfiles - with correct time stamps (not the wrong Dashboard time):

These errors are generated even if no computer is on (but two access points without an default gateway configured) - so I think we see an internal problem of the Astaro 7.075 ??
