Your swap space has bad blocks on the disk.

Try doing 

 # dd if=/dev/wd0s1c of=/dev/null bs=64k

which will try and read your entire disk (assuming your disk is wd0).

"Faults" is a term referring to how virtual memory works.  Basically, if
the CPU tries to access a page not in memory, it generates a fault, which
causes the OS to find and bring that page into memory.  Looks like your
system has been running for a while :-)
