rpc.statd is basically broken due to the new security "enhancements" added
in RH 7.0.  In effect, any lock requests to rpc.lockd fail because 
rpc.statd can't "monitor" anything.  This is due to rpc.statd not being
able to do just about anything after it starts (like accessng files).

The reason is that rpc.statd now chdirs to /var/lib/nfs/statd (which is
fine), then CHROOTS to "." !! Well, needless to say after the chroot
not much works since it can no longer access /etc, /usr/lib, etc.

I would suggest either removing the questionable "chroot" call or
making sure when installing that a full "anon ftp" sort of environment
exists under /var/lib/nfs/statd
