Well, at a quick glance, I can't see anything in either the NFS client nor
server that generates ENOTEMPTY for rmdir. It would seem to me that it
was generated by the underlying file system on the NFS server for some
reason. (Same goes for the syscall above the client side NFS.)

You could confirm this with a printf() right after VOP_RMDIR() in
sys/nfsserver/nfs_serv.c. (A tcpdump/wireshark trace would tell you
if the ENOTEMPTY was reported by the server, which looks like it is
the case.)

Not much help, but...rick
