Computer Model script related question

Hey fellow bit pushers,
I have been seeing an odd problem on a few of my systems and was wondering if any of you have seen it on your systems and possibly know why it happens.
We have a custom model script for a printer on our systems. This model script is just a standard ksh script but it calls a few compiled c programs to parse the -o options from lp as well as parse the c* file in /var/spool/lp/request/<printer> to find the name of the original file being printed. Some times on some of our systems after a reboot, the permissions of these binaries have been set from 550 to 440. The permissions on the actual model script in all it's various locations remains unchanged. It's like something is looking at our model script, finding all the binaries we are calling, and then chmoding them. This does not happen on all our systems and does not happen consistantly. As a work around I have written a script in /sbin/rc2.d to chmod them back to 550 after a reboot.
I have racked my brains out and HP wasn't any help (they tried hard though and I give them credit for that). I have been through all startup and shutdown scripts to no avail. I have been through every log on the system I could find and I can find no hint as too why this happens. I guess it might just be Unix Voodoo.
Thanks for any suggestions or answers,
Tony

reboot(8)						      System Manager's Manual							 reboot(8)

NAME
reboot - Restarts the machine SYNOPSIS
/usr/sbin/reboot [-dlnq] DESCRIPTION
When the system is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation. If no users are logged in, use the reboot command. The reboot command normally stops all running processes, syncs the disks, logs the reboot, and writes a shutdown entry in the login accounting file, /var/adm/wtmp. The reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard- ware time-of-day clock. After these activities, the system reboots. By default, the system starts and the file systems are automatically checked. If the start-up activities are successful, the system comes up in the default run-level. You must have root privileges to use this command. Using the -n flag can result in file system damage. FLAGS
Generates a crash dump of the system before halting it. Can be used with any of the other flags. Does not log the reboot using syslog Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not log the reboot using syslog EXAMPLES
To enable the default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the shutdown, and perform other routine shutdown and reboot activities. To shut down the system without logging the reboot, enter: reboot -l This command shuts down the system and performs all shutdown and reboot activities, except logging the shutdown. To reboot the system abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes. FILES
Specifies the command path Specifies the login accounting file Specifies the path of the syslog daemon RELATED INFORMATION
Commands: fsck(8), halt(8), init(8), savecore(8) shutdown(8), syslogd(8) Functions: reboot(2), sync(2), syslog(3) delim off reboot(8)
