But as no none else seems to be complaining since then, I’m wondering if there is a setting somewhere that I can’t seem to find that enables modules/cache maintenance. Or is everyone just manually purging?
Well, for future searches I did purge the entire directory with no apparent issues. Ran module admin, found a single update and installed also with no issues. So it appears safe to manually empty that directory in order to free up some disk space, 2.18gb in my case.
