Thanks go to Octave Orgeron who gave me the solution to my problem.
According to Octave, the directory was either a mount point for another
filesystem or perhaps a memory filesystem. So as suggested I tried doing a
umount on that directory:
/> umount /secdir
The size of the directory (as reported from 'ls -al') became 8192bytes, and
the directory behaved as an ordinary directory again.
The strange thing is that before doing a 'umount' on the directory, the
'mount' command didn't report any mounted filesystems at/in that directory.

Vinh Dang.
