If you look at the capture you will see that starting with frame 233006 10.0.0.18(mt-daapd) keeps resending the same TCP frame with SEQ 2207962 and never gets and ACK from 10.0.0.12(SoundBridge). Two minutes later SoundBridge sends a FIN packet (frame 233738) closing the connection. That’s why when mt-daapd sends another retransmit SoundBridge send back a RST since it already closed connecting.
So the problem looks to be that either packets were not delivered to SoundBridge or ACK replies were not getting back to mt-daapd.
