You have an enormous memory leak.

Swap cache: add 51244, delete 50404, find 25442/32337, race 0+13
And it's leaking highmem too, so it has to be user memory: pagecache or
anoymous RAM.
I'm not too sure what to do really - something odd is happening because if
this was happening generally then everyone in the world would be reporting
it.
I'd suggest you try switching compiler versions, try disabling unneeded
features in .config, see if you can identify any one which causes the leak.
Ideally, use `git bisect' to identify when the problem started occurring.
All very strange.
btw, what is this:
Starting readahead: [ OK ]
?
