It works for me very well. You must have a strange setup.

On my server:

# ls -l /var/lib/nfs/sm
total 0
-rw------- 1 root root 0 Aug 22 11:36 client 1 IP
-rw------- 1 root root 0 Aug 22 11:36 client 2 IP

On my client 1:

# ls -l /var/lib/nfs/sm
total 0
-rw------- 1 root root 0 Aug 23 08:01 server IP

On my client 2:

# ls -l /var/lib/nfs/sm
total 0
-rw------- 1 root root 0 Aug 23 08:01 server IP

BTW, there is no lock at this time.
