Mmmh, now that I think of it, I do have quota enabled on that
filesystem.
Due to the many many files, this may be what's causing the problem.
I thought quotas were supposed to work with 3.15, but maybe there is
still a leak?

I just turned quotas off and I'm going to let my server run for a while to
see if the leak stops.
