[icecast] Ices Spawing Zombie Perl Scripts - Again

So, I finally had some time to go through my scripts and after some poking and 
fixing I discovered that there is nothing wrong with my Perl script. It may be 
ugly and inefficient but it gets the job done and closes without throwing 
errors when run thru perl outside of ices.

However, ices continues to produce the defunct processes, a listing of ices 
and icecast2 related material from ps is listed at the end of the email. 
ices-ad.pm is the perl script used to produce the next song.

How and why is ices producing this behaviour and how can I stop it? I'm pretty 
sure that this is the likely cause of ices eventually Segment Faulting 
relatively regularily over time (defunct processes build up until it somehow 
crashes then it releases them).

Any ideas all?
