mac – What’s the “lsd” course of on OS X, and why is it utilizing a lot CPU energy?

I appeared in iStat Menus and observed {that a} course of named lsd was consuming 99% of my CPU (Out of 400% for 4 cores). I searched round for a bit, however could not discover out what this was, and why it is utilizing a lot processing energy. It is not Little Snitch Daemon, as I by no means put in that. Another person mentioned that it may very well be Launch Companies Daemon, however I believed that course of was launchd. It is Launch Companies Daemon.

Upon trying within the console, I discover these messages when looking for lsd:

As for this message:

22/12/2015 3:44:07.469 p.m. sudo[45308]:     MyUsername : TTY=ttys000 ; PWD=/personal/var/db ; USER=root ; COMMAND=/bin/mkdir lsd

I did attempt making a dir referred to as /personal/var/db/lsd as root.

Additionally, my CPU utilization appears to be very intermittent (which it by no means did earlier than).

Wanting into /usr/libexec, I discovered lsd and observed that it has been created on 17 Sep 2015. Why is it so new (together with all the things else in that listing)?
