Hi,

My system.log is filling up with lots of this error message below. ("spenser" is hostname).

Anyone seen this before? Know how to stop it?

Thanks in advance for any help.

Rowan.

    Yeah I'm getting it too.

    Are you using Internet Sharing? That's the only "new" thing I'm doing that seemed to cause this message.

    mDNSResponder is BonJour, it has nothing to do with DNS.

    Bonjour is itself a DNS (technically, a component of DNS Service Discovery that uses multicast DNS) though it is not user-configurable in the sense that, say, BIND is.

    The error message Bonjour is receiving is "DNS message too short." While I understand this may have little to do with a queryable DNS like BIND (though Bonjour is in fact a queryable DNS in an entirely different sense), Bonjour has everything to do with DNS.

    That said, I will be the first to admit that my ignorance on this topic is vast.

    <shrug> It's harmless... that's what logs are for... I'm surprised you think it bothers you.

    Of course the correct answer is to figure out what other machine is sending the bum zeroconf messages.
