<p>Obviously, if you run out of CPU, it's not entirely unreasonable for oddcast 
to have trouble of some sort. However, there should be absolutely _no_ way 
for this to crash icecast. Icecast is designed to be error-resiliant and not 
particularly timing-sensitive. If you can find any way to reliably crash 
icecast, we really, really want to fix it (being able to crash it with 
external input is generally a sign that there's - at the least - an 
exploitable DoS bug lurking somewhere), so we'd really like as much detail as 
you can give us.
