I've managed to get some more debug info in the logs. I cleared the log, changed the log debug level to 4 and started icecast, shout and a client. Here are some relevant lines from the log : CLIENT CONNECTION : [01/Mar/2001:11:36:58] [6:Connection Handler] Accepted client 2 from ... This client connection ends up as source thread 5. The first error is mentioned after about 20 minutes.

This happens after about ten seconds after the first mention of an error.

So, the errors all seem to pile up over about 30 seconds while not having had any errors before that. Is there someone who knows a bit more about the icecast source who could help me find out what these errors might mean and how I can go about solving them ? I'm keeping the debug logs if anyone is interested to take a look at them... thanks, thomas <-*- -*-> No matter how you try you'll never be as cheap as me when people have got no one else they can always sleep with me and no one else could be a better friend to you than me <-*- thomas at apestaart.org -*-> URGent, the best radio on the Internet - 24/7 ! - http://urgent.rug.ac.be/ --- >8 ---- List archives: http://www.xiph.org/archives/ icecast project homepage: http://www.icecast.org/ To unsubscribe from this list, send a message to 'icecast-request at xiph.org' containing only the word 'unsubscribe' in the body.
