Process (fmfd) spamming my console with sandbox denies

Since installing OSX 10.10 (Yosemite), my console is full of error messages regarding fmfd, like fmfd(384) deny file-read-metadata /Volumes/Macintosh HD This happens mostly at startup and when starting programs. I just want to know what it is, for my peace of mind and that my console can lose some weight ;) Here´s some more (hopefully useful) information from one report: fmfd(384) deny file-read-metadata /Volumes/Macintosh HD Process: fmfd Path: /usr/libexec/fmfd Load Address: 0x105f38000 Identifier: fmfd Version: ??? (???) Code Type: x86_64 (Native) Parent Process: launchd Date/Time: 2014-10-21 17:13:10.336 +0200 OS Version: Mac OS X 10.10 (14A389) Report Version: 8 Can you help me with that, or assure me it´s harmless? I don´t necessarily want to allow the process more rights in the sandbox if not necessary, like they did in https://discussions.apple.com/thread/5495141?start=15&tstart=0
