Hmm, historically flock was not NFS compatible, you were supposed to use
lockf or fcntl. I don't have an RHEL7 box at the moment, but the man
page for flock(2) on an RHEL6 box says:

       flock()  does not lock files over NFS.  Use fcntl(2) instead: that does
       work over NFS, given a sufficiently  recent  version  of  Linux  and  a
       server which supports locking.
