What is the "lsd" process on OS X, and why is it using so much CPU power?

I looked in iStat Menus and noticed that a process named lsd was consuming 99% of my CPU (Out of 400% for 4 cores). I searched around for a bit, but couldn't find out what this was, and why it's using so much processing power. It's not Little Snitch Daemon, as I never installed that. Someone else said that it could be Launch Services Daemon, but I thought that process was launchd. It's Launch Services Daemon. Upon looking in the console, I notice these messages when searching for lsd: 22/12/2015 9:36:02.000 a.m. kernel: Sandbox: AssetCacheLocato(400) deny(1) mach-lookup com.apple.lsd.mapdb 22/12/2015 9:36:02.931 a.m. AssetCacheLocatorService: LaunchServices: disconnect event received for service com.apple.lsd.mapdb 22/12/2015 9:36:02.000 a.m. kernel: Sandbox: AssetCacheLocato(400) deny(1) mach-lookup com.apple.lsd.mapdb 22/12/2015 9:36:02.932 a.m. AssetCacheLocatorService: LaunchServices: disconnect event received for service com.apple.lsd.mapdb 22/12/2015 9:36:03.000 a.m. kernel: Sandbox: AssetCacheLocato(400) deny(1) mach-lookup com.apple.lsd.modifydb 22/12/2015 9:36:03.657 a.m. AssetCacheLocatorService: LaunchServices: disconnect event received for service com.apple.lsd.modifydb 22/12/2015 9:39:41.000 a.m. kernel: Sandbox: SpotlightNetHelp(376) deny(1) mach-lookup com.apple.lsd.mapdb 22/12/2015 9:39:41.995 a.m. SpotlightNetHelper: LaunchServices: disconnect event received for service com.apple.lsd.mapdb 22/12/2015 9:39:41.000 a.m. kernel: Sandbox: SpotlightNetHelp(376) deny(1) mach-lookup com.apple.lsd.mapdb 22/12/2015 9:39:41.996 a.m. SpotlightNetHelper: LaunchServices: disconnect event received for service com.apple.lsd.mapdb 22/12/2015 9:39:42.000 a.m. kernel: Sandbox: SpotlightNetHelp(376) deny(1) mach-lookup com.apple.lsd.modifydb 22/12/2015 9:39:42.370 a.m. SpotlightNetHelper: LaunchServices: disconnect event received for service com.apple.lsd.modifydb 22/12/2015 9:39:58.100 a.m. lsd: LaunchServices: Could not store lsd-identifiers file at /private/var/db/lsd/com.apple.lsdschemes.plist 22/12/2015 10:01:15.000 a.m. kernel: process lsd thread 19967 caught burning CPU!; EXC_RESOURCE supressed due to audio playback 22/12/2015 3:34:04.828 p.m. lsd: LaunchServices: Could not store lsd-identifiers file at /private/var/db/lsd/com.apple.lsdschemes.plist 22/12/2015 3:44:07.469 p.m. sudo: MyUsername : TTY=ttys000 ; PWD=/private/var/db ; USER=root ; COMMAND=/bin/mkdir lsd 22/12/2015 3:49:09.183 p.m. lsd: LaunchServices: Scheme mapping file does not exist, creating file. 22/12/2015 3:49:09.400 p.m. lsd: LaunchServices: Could not store lsd-identifiers file at /private/var/db/lsd/com.apple.lsdschemes.plist 22/12/2015 3:49:09.407 p.m. lsd: LaunchServices: Could not store lsd-identifiers file at /private/var/db/lsd/com.apple.lsdschemes.plist 22/12/2015 3:49:39.366 p.m. lsd: LaunchServices: Currently 0 installed placeholders: () 22/12/2015 3:49:50.000 p.m. kernel: Sandbox: AssetCacheLocato(535) deny(1) mach-lookup com.apple.lsd.mapdb 22/12/2015 3:49:50.802 p.m. AssetCacheLocatorService: LaunchServices: disconnect event received for service com.apple.lsd.mapdb 22/12/2015 3:49:51.000 p.m. kernel: Sandbox: AssetCacheLocato(535) deny(1) mach-lookup com.apple.lsd.modifydb 22/12/2015 3:49:51.002 p.m. AssetCacheLocatorService: LaunchServices: disconnect event received for service com.apple.lsd.modifydb 22/12/2015 4:31:57.573 p.m. lsd: LaunchServices: Could not store lsd-identifiers file at /private/var/db/lsd/com.apple.lsdschemes.plist 22/12/2015 4:34:34.075 p.m. lsd: LaunchServices: Could not store lsd-identifiers file at /private/var/db/lsd/com.apple.lsdschemes.plist 22/12/2015 4:34:34.290 p.m. lsd: LaunchServices: Could not store lsd-identifiers file at /private/var/db/lsd/com.apple.lsdschemes.plist 22/12/2015 4:37:20.000 p.m. kernel: process lsd thread 26462 caught burning CPU!; EXC_RESOURCE supressed due to audio playback As for this message: 22/12/2015 3:44:07.469 p.m. sudo: MyUsername : TTY=ttys000 ; PWD=/private/var/db ; USER=root ; COMMAND=/bin/mkdir lsd I did try making a dir called /private/var/db/lsd as root. Also, my CPU usage seems to be very intermittent (which it never did before). Looking into /usr/libexec, I found lsd and noticed that it has been created on 17 Sep 2015. Why is it so new (along with everything else in that directory)?
