[Pianod] Pianod2 hangs on network stall

[Chris Greenman]

Hello,

    I apologize if this has been discussed before.   The archive search
isn't working.

    I've got a Raspberry Pi 3 that I'm setting up as an on-board boat
computer and media server.  Typically when I go out I use my phone as a
wifi hotspot for Internet.  As such the network can come and go but what
I'm seeing is that Pianod2 seems to hang on network loss and will not
restart when the network returns.  The only way to get piand running again
is to totally kill it and restart.  A HUP does nothing and it will not
start when play is pushed or a different playlist is selected.  I know the
audio still works because I have another process that speaks speed and time
to the same audio sink.

I'm running Raspbian Jessie with pianod2-213 compiled from source.  My
physical setup is as follows:

 __________        ___________        __________________       _________

                                                                   |

I made sure that all the wifi are on different channels.  At home (where I
have much more 2.4ghz interference) everything works perfectly and the
network is stable.  on the boat the LTE coverage is a little spotty which
causes network hiccups and stalls pianod.

I've tried running nc on 4445 and is doesn't show anything out of the
ordinary.

Any suggestions would be greatly appreciated.

Thanks,
Chris
