I don't know when it started, recently I guess, but I keep getting three new entries in my console every three seconds (!!!). It is always the same entry: mDNSResponder: queryrecord_result_callback: mDNS_Lock: Locking Failure! mDNS_busy 1 != mDNS_reentrancy (see picture). It's very worrying. I have been looking everywhere for help. I have installed HandsOff recently but I have also installed it on another Mountain Lion computer and the entry does not show. If I run this sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist it obviously stops but then I can't use the Internet. Any idea highly appreciated!!
