Remember, a page fault isn't a bad thing.  It just means the process has a paged swapped out:

> ::ps -f !grep 15776
R  15776   2671     10     10      0 0x4a004000 ffffff075dadd0a0 perl /var/web-gui/data/scripts/agent-nappit.pl '1474140713_hmp' ''

And THAT was the particular process running.

SO you've 4G of swap on rpool.  Typical out of the box deployment.

Something corrupted the anon cache entry, making it point to something in unused/unallocated/un-something hyperspace.  The big question is what.  This is why I asked about your hardware.  It wasn't obvious, but since you're running NAPP-IT, I assume you're using ECC memory?
