DESCRIPTION
        FAM, the File Alteration Monitor, is a subsystem that applications can
        use to be notified when specific files or directories are changed.  It
        is intended as a replacement for mechanisms such as poll and select.
....

So indeed that potentially can have something to do with your
problem if the process polluting your cache wants the FAM service
and doesn't get it and then falls back to something insane.

And there's still the bug addressed here:
<https://gitlab.freedesktop.org/fontconfig/fontconfig/commits/master>
but seemingly not appliying to your case when fc-cache is switched off.

Have you tried disabling time-sliderd, to check if its lock mechanism
triggers the font cache updates ?
