[Icecast] fallback time

[Stéphane Péron]

Hi
I have an icecast server that relay a remote stream, with a local 
fallback mountpoint. When I unplug the network cable (just for test), 
icecast falls back to the local mountpoint after a few seconds. When I 
re-plug, I have to wait 1or 2 minutes before moving back to the remote 
stream. Why is it so long ?
I'm using the default parameters, with a 128 kbps stream.
