Page faults with physical I/O mean different things on different
operating systems. On some, it is an indication of process swapping
from or to disk. On others, it is an indication of virtually any disk
I/O (e.g., logging) taking place. You may want to consult your OS
documentation to find out what it means in your environment.
You can ignore this OS-level statistics unless you have other problems
that may indicate that your Polygraph processes are running out of
memory and swapping out.
