Your swap space has bad blocks on the disk.
Try doing
# dd if=/dev/wd0s1c of=/dev/null bs=64k

"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
