You can differentiate these in the /proc/$PID/status file. VmRSS is sum
of three parts, and RssFile is the one for mapped files. I agree this
part is basically disk cache, though Knot maybe assumes it *won't* be
swapped-out (performance-wise).
But the problem in this case is probably to understand what exactly
consumes the memory...
