one of my roles at work is 'testing' of bespoke inhouse software, so i know the following question is going to grind you, but <clenches>;
.. by "intermittent", do you mean 'most of the time'? - we've never had it work.. you can merily sit there randomly clicking on 'Kick' across any of the 30+ listeners without affecting anyone's listening ability..
AND/OR
is it 'intermittently decided' at each start of the shoutCast daemon/program?
AND/OR
is it 'intermittently decided' when each listener connects?
....
sorry

/hugs
