21474836480 = overflow.

This is 500,000,000 in hexadecimal. (500 million)

BTW, your output is extremely specific on your settings in date and such. It depends on whether I want to display the month or not.
There is a -ls option in find; no need to pipe this through xargs.

So try

$ find . -type f -ls | awk '{print $7}'

This should give a much smaller footprint on your CPU load.
Maybe this "fixes" the "bug" you reported as well,
