We've been getting this error intermittently:
Problem sending data to a server. Please check network upload speed (Output 1)
We're running a stable connection, nothing else on the same network has any issues, and it seems to interrupt our feed to the streaming server. Thinking it was a Shoutcast issue, we switched to Icecast, and it seemed to be ok, but now the issue is back.
Possible cause could be we are running low on HD space, but any other suggestions would be appreciated.
