Fuser on VXFS not reporting processes

I have a perl script like :

Code:

#! /usr/bin/perl
open FILE1,">/tmp/openfile.test.out";
open FILE2,"</tmp/openfile.test.in";
open FILE3,">/data/openfile.test.out";
open FILE4,"</data/openfile.test.in";
        <STDIN>;
close FILE1;
close FILE2;
close FILE3;
close FILE4;

/tmp is jfs2
/data is vxfs

Fuser does not report processes on /data/openfiles.test.in where it does report a processid on /tmp/openfiles.test.in

Code:

 # fuser /tmp/openfile.test.in /data/openfile.test.in
/tmp/openfile.test.in:  1507428
/data/openfile.test.in:

Are there known problems with fuser on vxfs?

The system is running AIX5.3 in a LPAR.
/data is a SAN disk that is offered by a VIO to the LPAR.

Addition: I found that procfiles does see the open file but cannot stat the file name.

Code:

procfiles -n 675910
675910 : perl openfile.pl
  Current rlimit: 2000 file descriptors
   0: S_IFCHR mode:00 dev:10,4 ino:1181 uid:0 gid:0 rdev:19,1
      O_RDWR  name://dev/pts/1
   1: S_IFCHR mode:00 dev:10,4 ino:1181 uid:0 gid:0 rdev:19,1
      O_RDWR  name://dev/pts/1
   2: S_IFCHR mode:00 dev:10,4 ino:1181 uid:0 gid:0 rdev:19,1
      O_RDWR  name://dev/pts/1
   3: S_IFREG mode:0444 dev:10,7 ino:446 uid:0 gid:0 rdev:0,0
      O_RDONLY size:0  name:/tmp/openfile.test
   4: S_IFREG mode:0444 dev:34,3000 ino:8 uid:0 gid:0 rdev:0,0
      O_RDONLY size:0  name:Cannot be retrieved

meld

MELD(1) 						      General Commands Manual							   MELD(1)

NAME

       meld - Visual diff and merge tool for the GNOME Desktop

SYNOPSIS

       meld [options]
       meld [options] FILE1
       meld [options] DIR1
       meld [options] FILE1 FILE2 [FILE3]
       meld [options] DIR1 DIR2 [DIR3]

DESCRIPTION

       Meld  is  a  graphical diff viewer and merge application for the Gnome desktop.	It supports 2 and 3-file diffs, recursive directory diffs,
       diffing of directories under version control (Arch, Bazaar, Codeville, CVS, Darcs, Git, Mercurial, Monotone, RCS), as well as  the  ability
       to manually and automatically merge file differences.

OPTIONS

       --auto-compare, -a
	      Automatically compare all differing files on startup.

       --diff FILE1|DIR1 FILE2|DIR2 [FILE3|DIR3]
	      Create a diff tab for the given files or directories.  Note that "meld --diff FILE1 FILE2" is functionally equivalent to "meld FILE1
	      FILE2".  However, the --diff argument can be given multiple times for one invocation of meld which allows the user to  automatically
	      initiate multiple diffs when meld starts.  See examples below.

       --help, -h
	      Print application help and usage.

       --LABEL=<label>, -L <label>
	      Set application window title to <label>.

       --version
	      Print application version and exit.

EXAMPLES

       meld
	      Run meld without initiating a diff.

       meld FILE1
	      Initiate a diff between FILE1 and the version-controlled copy of FILE1.

       meld DIR1
	      Initiate a recursive diff between DIR1 and the version-controlled copy of DIR1.

       meld FILE1 FILE2
	      Initiate a diff between FILE1 and FILE2.

       meld FILE1 FILE2 FILE3
	      Initiate a 3-way diff between FILE1, FILE2, and FILE3.

       meld DIR1 DIR2
	      Initiate a recursive diff between directory DIR1 and DIR2.

       meld DIR1 DIR2 DIR3
	      Initiate a recursive 3-way diff between directory DIR1, DIR2, and DIR3.

       meld --diff FILE1 FILE2 --diff FILE3 FILE4
	      Initiate a diff between FILE1 and FILE2, and a separate diff between FILE3 and FILE4.

BUGS

       If  you	find  a  bug,  please report it at https://bugzilla.gnome.org/buglist.cgi?product=meld or mail a description of the issue to meld-
       list@gnome.org.

AUTHORS

       See the AUTHORS text file in meld's source code (http://git.gnome.org/browse/meld/tree/AUTHORS).
