in Linux, I test about ulimit and WebLogic. I set soft limit and hard limit differently, but process's soft limit and hard limit is same. Why they have same value?

# Set Soft limit
[was@was10 bin]$ ulimit –S -n 2048
# Check Soft limit
[was@was10 bin]$ ulimit -S -a
……
open files                      (-n) 2048
……
# Check Hard limit
[was@was10 bin]$ ulimit -H -a
……
open files                      (-n) 4096
……
# restart Weblogic and check limits
[was@was10 bin]$ cat /proc/$PID/limits
Limit                     Soft Limit           Hard Limit           Units
……
Max open files            4096                 4096                 files
……
# They have same value 4096
