I just checked my network connections on the raspberry when investigating an other problem…
32 open http connections to the receiver, doesn’t sound right and could be responsible for some problems as the receiver has very low processing power.
Ither the connections are not properly closed or not properly reused. You could take a look at my Harmony plugin, had similar problems and introduced some kind of connection pooling. This also made it faster for me as you don’t need to create a new connection everytime a command is sent or some value is polled.
