du and df do not match on NFS share
Here is the scenario...
NFS share that is accessed every few minutes by approx 70 systems (AIX 5.3/6.1). Filesystem space is being eaten up rapidly according to df however du numbers really never change. lsof and fuser cannot see any unlinked files on either the NFS server or remote clients. Restarting nfsd does not resolve the issue. However, attempting to umount the underlying JFS2 filesystem fails (device busy) obviously but magically frees up the "used" disk space...
Any thoughts on this?

NFSD(8) BSD System Manager's Manual NFSD(8)
NAME
nfsd -- remote NFS server
SYNOPSIS
nfsd [-6rut] [-n num_threads]
DESCRIPTION
nfsd runs on a server machine to service NFS requests from client machines. At least one nfsd must be running for a machine to operate as a
server.
Unless otherwise specified, four servers for UDP transport are started.
The following options are available:
-r Register the NFS service with rpcbind(8) without creating any servers. This option can be used along with the -u or -t options to
re-register NFS if the portmap server is restarted.
-n Specifies how many server threads to create. The default is 4. A server should run enough threads to handle the maximum level of
concurrency from its clients.
-6 Listen to IPv6 requests as well as IPv4 requests. If IPv6 support is not available, nfsd will silently continue and just use IPv4.
-t Serve TCP NFS clients.
-u Serve UDP NFS clients.
For example, ``nfsd -t -u -n 6'' serves UDP and TCP transports using six threads.
nfsd listens for service requests at the port indicated in the NFS server specification; see Network File System Protocol Specification, RFC
1094 and NFS: Network File System Version 3 Protocol Specification.
The nfsd utility exits 0 on success, and >0 if an error occurs.
