If that's the explanation, how could it be
detected/measured/investigated/resolved/prevented?

Under ordinary circumstances, machines will go run like this for days/weeks:

Mem: 549M Active, 3623M Inact, 567M Wired, 3484K Cache, 827M Buf, 3156M Free
Swap: 1024M Total, 1024M Free

Then, when this happens, it rapidly degrades from that to so bad that
processes start getting killed for being out of swap space.

Thanks!
