Note: Shoutcast V1 streaming to a Shoutcast V2.5.x server seems to be problematic. The newer server tracks MP3 boundaries in order to insert advertising and this appears to have problems keeping sync with the MP3 stream. I spent significant time eliminating MP3 framing errors in my code. You can see these 'Bad frame' errors in the sc_serv.log and the shoutcast server will eventually reset the connection after a period of time or after a number of framing errors occur. I anticipate that streaming to a Shoutcast V2 server using the ultravox (ie V2.x) protocol may resolve this issue.
