iPhone stream keeps stopping

If I listen to a very long video (30m+) the stream will randomly stop. After that, I have to restart the server and phone to be able to play more than a few seconds of video. Sound like anything familiar?

Which iPhone is it? What kind of PC is this running on? Is the CPU on PC high during streaming?

iPhone 4S
Pc: i7 860, CPU is never above 20%
I don’t think it’s a transcoding issue, but something to do with the streaming.

It is now only playing for around 10 seconds before stopping

Thanks, we will look into that and try to reproduce.
