tracking down nfs stats

tcpdump on my machine indicates:
09:09:03.835014 IP mouse.2280902084 > trout.nfs: 144 fsstat [|nfs]
09:09:03.835208 IP trout.nfs > mouse.2280902084: reply ok 168 fsstat [|nfs]
09:09:04.331178 IP mouse.4224086465 > trout.nfs: 144 fsstat [|nfs]
09:09:04.331382 IP trout.nfs > mouse.4224086465: reply ok 168 fsstat [|nfs]

and so on approximately every 0.5 sec. How do I track down what process is doing this?
I have some guesses, but is there a more principled way of going about it than killing things one by one?

Oh wait, lsof -N does it, I think? Ok, then, how do I track down what’s causing a process to respawn? ps axf indicates it has no parent which means it just daemon()‘d?
