AFAIK Fedora uses the available RAM as a) buffer space, and b) the /tmp

BTW a slightly more user-friendly way to get that info is with the
free(1) command.
The joke is, the >60GB of missing memory doesn't even show up in free:
$ free
total used free shared buff/cache
available
Mem: 2400708 1093732 284844 121920 1022132 957848
Swap: 62499836 0 62499836
For some reason the kernel marks it as reserved.

Try installing htop ("$ sudo dnf install htop"), run it, press F6 and

Same goes for htop. It's showing I have 2.29G of memory.
Update: I upgraded from Fedora 27 to Fedora 28, and the same issue
persists. Of course, the kernel is almost the same.
I'd try a newer kernel from the 4.17 series from the non-official
kernel repo for Fedora, just to narrow down the issue and see, whether
it's really a kernel thing:

I've had issues here, too, on F27, and at least one of them seems to
be gone with such a kernel:
% uname -r
4.17.2-250.vanilla.knurd.1.fc27.x86_64
HTH, and Regards.
Good luck!
