Stops listening on UDP port after getting invalid json

[elecnix]

This will cause prompush to return from the listenUDP function, causing it to close serverConn:

echo "hello" | nc --udp localhost -p 9090

logs:

2016/11/09 17:20:37 udp.go:36: Error: invalid character 'h' looking for beginning of value

then a second nc prints:

Ncat: Connection refused.

Thanks for opening an issue @elecnix! I've asked a colleague to confirm the issue and hopefully we can patch it a.s.a.p.

The issue should be resolved with the latest release @elecnix. Let us know if you find the same to be true!

Thanks!
