Hello,
I have some cases that souce icon inform that are no source online and auto dj indicator is online and server icon show online too. Seems that sc trans v2 down and system not detect that. When client try to stop and start the server it not have sucess, because the shoutcast server is still alive, it not are finished with the stop server command. So we need enter via ssh and kill the process wiht sudo kill -9 command. After that it starts again.
I believe that could be caused by some kind of bug in mp3 / sc_trans v2, but system could detect and kill the processes correctly, or try some restart.
