Hi,

The NFS server is running FreeBSD 6.0, and no problems with other NFS client
with FreeBSD 6.

When a new client with FreeBSD 7 comes, the NFS server always says:

Apr  2 03:52:01 xxxx rpc.lockd: clntudp_create: RPC: Program not registered
Apr  2 03:52:01 xxxx rpc.lockd: Unable to return result to 192.168.4.248

The 192.168.4.248's OS is FreeBSD 7, and it can successfully mount the
directories on NFS server.

It seems something wrong with rpc.lockd ? The 'rpc.lockd' seems totally
different in FreeBSD 6 & 7.

How should I fix this problem?  Thanks!
