Here is the Answer to my question below:
Thanks very much to those of you who help.
The below document is from Sun Microsystems explains that.
#################Start of doc####################
Bug ID Synopsis Date
1224920 Cannot create more than 32, 767 files in a directory 20 Aug 1996
Category kernel
Subcategory ufs
State closed
Release Summary 5.4
Integrated in Releases (none)
Patch ID (none)
Description Top
If you take a bare directory and create 32,767 files in it all is ok. Run
fsck
and it completes fine.
Add 1 more file to the directory, total now 32768 and then run fsck and the
inodes become corrupt as the link count goes negitive.
>From /usr/include/sys/param.h:
#define MAXLINK 32767 /* max links */
This has been reproduced in our lab by simply creating 32,767 files, adding
1
more and running fsck. Test systems 4.1.3_U1 and 2.4 with current patches.
Work Around Top

I suggest that the customer consider breaking down the entries in the
directory
into subdirectories. For example, /home/abcdefg could be broken down into
/home/a/abcdefg or (if necessary) /home/a/b/c/d/e/f/abcdefg.
