I'm trying to understand why mdworker is always at 100% even when (apparently) not indexing. If I open Spotlight, there's no message telling me that a drive is being indexed. If I run fs_usage -w -f filesys mdworker
, there's also no output.
Just to be sure, I've tried stopping and restarting the Spotlight service so it rebuild the db from scratch. I've let it run for about 12 hours but it's still running now at 100%. I've also excluded many folders from indexing.
Any idea what could be the issue? Is there any way to know what the process is actually doing?
