What does your "nfsserver" script do to try to stop/restart the nfsd? For a very long time the approved way to stop nfsd has been to run "rpc.nfsd 0". My guess is that whatever script you are using still trying to send a signal to nfsd. That no longer works.
Unfortunately the various sysv-init scripts for starting/stopping nfsd have never been part of nfs-utils so we were not able to update them. nfs-utils *does* contain systemd unit files for sites which use systemd.
If you have a non-systemd way of starting/stopping nfsd, we would be happy to make the relevant scripts part of nfs-utils so that we can ensure they stay up to date.
Actually, we use service nfsserver restart => /etc/init.d/nfsserver =>
stop_nfsd(){ # WARNING: this kills any process with the executable # name 'nfsd'. echo -n 'stopping nfsd: ' start-stop-daemon --stop --quiet --signal 1 --name nfsd if delay_nfsd || { echo failed echo ' using signal 9: ' start-stop-daemon --stop --quiet --signal 9 --name nfsd delay_nfsd } then echo done else echo failed fi }
