/usr/local/etc/rc.d getting run twice

[Geoff Sweet]

Greetings, I have new freshly installed servers of FreeBSD 6.3. We
started our migration before 6.4 was released.  Anyway we have some
custom tools that we have built startup scripts for and placed them
into /usr/local/etc/rc.d.  However the problem is that these tools get
called twice to startup.  Thus leaving us with two instances of the
tools running.  

I've read a thread similar to this question in the mailing list archive
however it had to do with upgrading and didn't seem to apply to my
issue.  I've added a buch of logic to the script to try to determine if
the tool is running or not, but that seems like band aiding the issue
instead of fixing the problem.

Any advice?
