Comment 12 for bug 1972159

In my case that was occurring compiling the kernel. The process take 6 hours and crash without finished in three occasions. See:
https://gitlab.freedesktop.org/drm/amd/-/issues/1569#note_1409226

To ensure it finished, I released the cache several time in the process:
sudo sh -c " sync; echo 3 > /proc/sys/vm/drop_caches"

When I do that all was ok, but sure is not nice to have a process running with an interval time to observed and cleaning the cache if it's to high.
