thx for your quick reply...

I have no idea about streamtranscoders tolerance either (it's config-file
doesnt say anything about it). I also increased the source-timeout already
to 30 sec., without any succes - what's happening is that icecast switches
to the fallback-stream I have defined. 

I thought it might help to increase the upstream-buffer...so, the when my
source is off the net, the outtake can be bridged by icecast, but if I
understand u correctly that's not possible?

greets,
mike

30 seconds is a large outage, don't be surprised if streamtranscoder
will drop/block connection on full socket.

The only lag that is added by icecast is the burst buffer, nothing else
is added to that.  You're better off falling back then bringing
listeners back after resuming.  The development code can fallback to
file which may be helpful to you as well.
