com.apple.xpc.launchd & com.apple.mdworker.bundles pollute logs with errors

I made a clean install of Yosemite to MacBook Pro (13-inch, Early 2011), and restored documents and apps from TM backup, no problems so far, but I observe following repeating messages in system log and it concerns me, because apparently, launchd is trying to do something related to spotlight, but fails and this happens every 10 seconds.. I see no suspicious activity apart from too much CPU time spent on mds and mds_stores (but I guess it's due to fresh install, hence Spotlight needs to index everything...).

Any ideas where to dig?

Thanks for the hint; deleting (not chown’ing) 502-owned folders/files in the /var subdirectories definitively helped (after a reboot, of course). In addition I found a 502-owned app bundle in /Applications that I chown’ed to me (501).

Though, no idea what is spawning these 502 attributions. A user 502 didn’t exist on my system.

Thanks for the UID advice. This has just fixed my issue with the new Photos.app where it was hanging indefinitely 5 seconds after launch. Problem solved. I wonder how many other issues it has solved.
