[sf-perl] 100 levels deep in subroutine calls!

What I have learned today is that Perl has a default recursive setting
of 100.  It turns out that someone had removed the Oracle path
definition file that the program needed and when it couldn't find the
file, it went to perform the email notification sub-routine.  The
problem is that the email notification sub-routine also require the
Oracle path to be set so it also calls this sub-routine that reads this
file to set the Oracle paths.  So the program quickly reached the
limitation of 100.  From this exercise I was able to identify a flaw in
the design of the notification sub-routine.

So back to my original problem of the core dump.  Haven't identified
this problem.

I'd be much less interested in an apology and much more interested in a
disclosure of what you learned so that future readers of this thread
will also be able to follow your enlightenment.

How were you, in fact, recursing?  That'd be a good thing to disclose.
