Well, swap is strange all right, but what's so strange? The fact the numbers
don't add?. To that, I don't know the answer but other than that, it's pretty
clear you have reserved all of your swap space but is not being used (yet). You
can add new swap (swap -a) or activate virtual swap, which given the low
ammount of swap you have and the large files in use , I wouldn't advise to do.
I would really try to get more RAM and then increase the swap space.

There was a thing about arena size posted last year or a couple of years ago.
Check the archives, I think it had a limit under 32bit addressing or something
