Hi Romain, That's what I actually did, but I can't find any obvious reason. I start to get those catchup messages as soon as I start liquidsoap, so I think it has something to have with the way my script is organized. But first I would like to know what is the usual cpu usage level for typical liquidsoap process? 'cause right now I'm sure that for my server (2 x Intel(R) Xeon(R) CPU E5405 @ 2.00GHz (quad-core dual processor), 8GB RAM), will really get overloaded if I launch any more channels (15 running at the moment). Is it normal?
