I have libvirt configured to run LXC by default.
I also have memory limits in place. Directly after starting the LXC
containers, they are correct; e.g.:

root@dns:~# free
               total        used        free      shared  buff/cache   available
Mem:        1048576       41660     1006784       48124         132     1006784
Swap:             0           0           0


After some time, I have noticed that they are no longer correct; in fact
they are wildly wrong:

root@dns:~# free
               total        used        free      shared  buff/cache   available
Mem:    9007199254740991      598372 9007199254108535       85652       34084 
9007199254108535
Swap:             0        1692       -1692

I suppose, this is from within the container?

How do you apply/setup the limits?
