That's your problem then. ramfs is, like the name suggests, a filesystem that
resides in memory. mount will ignore the /dev/sda you specified and just
create a ramfs instance at /mnt/usbkey. Try umounting it and remounting it and
you'll see that the contents disappear. If you specify ramfs without any
options the default behavior is to create a ramfs with a maximum size of one
half of physical memory. ramfs only consumes memory for what you're using, so
when you started copying stuff in there it started to grow and apparently the
rest of the system was already using more that half of the memory so once the
ramfs got big enough it triggered the OOM.
I think this bug can be closed, ok Alex?
