sharedfilelistd and distnoted hog CPU

I understand from my findings on the topic that sharedfilelistd is an "agent that is used by applications to read/modify recent documents/servers/hosts" and distnoted a "distributed notification services".

What I don't understand is why those two process very frequently start using between 130 and 200% of CPU (Monitor).

I tried various combinations of apps loaded or not that would be causing the problem, but I was unable to discern a pattern.

I can't tie this issue with any noticeable event (update, install, config tweak, ...).

Any idea ? (while I continue looking into possible causes)

Config: MacBook Air (13-inch, Early 2015) High Sierra 10.13.4 2,2 GHz Intel Core i7 8 Go 1600 MHz DDR3 Intel HD Graphics 6000 1536 Mo

I had the same problem with sharedfilelistd consistently taking over 100% of my CPU. I don't have file sharing enabled.

I opened up Terminal and found the processes with pgrep -lf sharedfilelistd, noticing two of them running; that might have indicated a problem. I killed both with sudo pkill sharedfilelistd and they terminated and one restarted, presumably via launchd.

After the single process returned, it took between 30-75% of my CPU, perhaps averaging 50%, and my machine is back to normal. There might be some impact to some service I'm not aware of or do not use, but this worked for me.

Relaunching the Finder helped for me.
