Thanks for the responses.............

I just received another response from Neil:

This behavior is specific to SLES9 and SLES10.  The kernels in those
distributions contain statd functionality and use the same port as
lockd uses.

You cannot in SLES9/10.  On other systems where statd is a user-space
program, they cannot be the same port.


> Is there any problem with statd using the same port as lockd ?

Not on SLES9/10.

Alan responds:

I think this will cause one of them to fail to function.  You can't
actually have two processes bind to one port.  Even if you could, only one
of them would get the connection.  This might result in the client lock
request going to the statd, or the client status request going to the
lockd.

I have posted this question to :  nfs@lists.sourceforge.net   with no
response yet.

Any assistance on this would be appreciated.


I noticed that when I set the lockd (lockmngr) ports to a specific static
port that the statd (status) port is set to the same port.
