Why no stopping service when reboot...

[Steven Shiau <steven@xxxxxxxxxxx>]

Hi! 
I wrote a service to create and clean a swap file when boot or reboot a
machine.
By using "chkconfig --add mkswapfile", it's successfully added to the
/etc/rcx.d. I do saw S15mkswapfile in /etc/rc3.d, and K85mkswapfile in
/etc/rc6.d, and it DO run successfully when my machine booted. BUT when
the machine rebooted, it did NOT run K85mkswapfile at all. I can NOT
even see anything, it seems that init just skip it. 
Does anyone know why ?

Thanks in advance.

Ps. The mkswapfile script is:
-------------------------
#!/bin/sh
# mkswapfile    This shell script takes care of starting and stopping
#               the mkswapfile.
