[CentOS] Init.d script troubleshooting.

I got a strange problem with init.d scripts on a fully updated (as of today) fresh install of 5.5 x64.

I've written a script, /etc/init.d/Fast that starts a fairly large and slow commercial application, by calling that applications control binary to do the actual work.

I "registered" the script, via chkconfig --add Fast, and the symlinks are in the expected places.

[root at rpmbuilder etc]# ls /etc/rc*/*Fast
/etc/rc0.d/K10Fast  /etc/rc4.d/S90Fast
/etc/rc1.d/K10Fast  /etc/rc5.d/S90Fast
/etc/rc2.d/K10Fast  /etc/rc6.d/K10Fast
/etc/rc3.d/S90Fast

[root at rpmbuilder etc]# ls -la init.d/Fast
-rwxr-xr-x 1 root root 2691 Nov  9 16:49 init.d/Fast
[root at rpmbuilder etc]# 

Testing the script, both via "/etc/init.d/Fast start" and "service Fast start" works, and it fully works for the implemented "start","stop","status" commands.

"/etc/rc0.d/K10Fast stop" works as expected. (as does /etc/rc1,2,6 etc..)

The script contains full paths to everything.

At boot, the script functions as expected.

My problem is that at reboot, via shutdown -r or shutdown -h the script does NOT get called, so naturally the system doesn't get to clean up after itself, then it fails to startup correctly next boot.

The startup and shutdown of this application is slow, 2+ minutes. I know it doesn't work at reboot or halt because the host goes down fast, and the system is littered with left over pid files and such that prevents a clear restart of the Fast process.

I've placed echo commands in the script, both in the stop() function to log the date/time to a file when it's called, and in the head of the script itself, just to see if it gets called at all during shutdown. 

As far as I can tell, the script does NOT get called at shutdown/reboot time. At all.

I'm just confused, this ain't supposed to be this hard... Is there some way to debug init?

Suggestions?

Thanks
