Time or data limit?

[tardolus]

Hey.

I have "normal" Shoutcast in use. I manage my own stream.

Is there time or data limitation when streaming? Because after about 6-12 hours of streaming no one cant connect to my stream even if it's up and sending data successfully.

IP hasn't changed, that's not the problem.

I air on a cafeteria with 128 kbps (mono) as a background music.
