The server running on your home machine is supposed to set up a connection to a client who wants to listen to music (yourself sitting at work, somebody streaming to an app etc).
What we see in the logs is an error reported by the server. It tells that when the server tried to send more data to the client, the connection was interrupted. The server itself didn't try to close it, it happened unexpectedly and the server reports it as an error.
This could either be a client disconnecting in an uncontrolled manner (imagine a mobile app running out of battery for example), or it could be non-working infrastructure. A firewall that decides that the type of traffic / your ip is not trusted. Some complicated NAT setup that's poorly configured. A wireless router that's dropping connections. A network card that's getting old. We have no idea from the log, we can just tell that communication is interrupted when the server tries to send data to clients.
Here's another thread for another person with similar problems:
viewtopic.php?f=2&t=10265. In his/her case, the solution was to upgrade network card drivers. I don't think it is an error with the application and the only knowledgeable person who can track down possible reasons for a case like that is you. Maybe not much help but hope it gives some clue!
