True.
But then, not over network hops that drop port 2049, either. Break the
assumptions underlying the 'net and you have to expect breakage from
stuff built atop it.

Not for NFS through a (stateful) filtering router, no. Reboot the router,
and you will have to walk up to every client and reboot it. With NFS over
UDP, the clients will recover.

If you go back a few years, you can find a thread where I reported tstile
lockups on PPC. I don’t remember the details, but it was back in 6.1 as I
recall. This is not a new problem, and not limited to NFS. I still have a
similar problem with my 7.2 system, usually triggered when I do backups

Thanks to riastradh@, this tuned out to be caused by an (UDP, hard) HFS mount
combined with a mis-configured IPFilter that blocked all but the first fragment
of a fragmented NFS reply (e.g., readdir) combined with a NetBSD design error
