Hi hce,

You use NFSv3, 
the NFSv3's file lock service depend on NLM(Network Lock Manager),
that need a user space program named rpc.statd to support service
like this:

           |     nfs client     |      nfs server 
-------------------------------------------------
           |                    |
user space |     rpc.statd    <--->      rpc.statd
           |        ^           |            ^
--------------------|------------------------|----
           |        v           |            v
kernel     |      lockd       <--->       lockd

when your nfs client is a MAC, maybe Mac's user space don't support
a program as rpc.statd, or you don't make the program run correctly.

Maybe you can use NFSv4 to avoid this problem.
