[Icecast] IceCast KH - question

[Live Mix - Arvy]

Hi there,

we use IceCast KH on our webradio, no commercial. We have an issue that 
we dont know where to look. When listening using WinAmp (but in other 
players too like JW Player), after 70 or 90 minutes, we realize that the 
"green square" on top of WinAmp becomes a "red square". About 60 minutes 
after start, sometimes the "red square" blinks, and then more 
frequently. It happens with different internet connections and 
providers. Until 60 minutes, the broadcast is perfect.

Can you give me an idea where to look or solve this issue? It's related 
to Icecast, or encoder, or internet connection, etc?

Thank you
