couldn't find source 1 for /ping message

[Tk Youn]

Hello SonoBus Users,

I am using SonoBus package installed on Raspberry Pi 3B by Jack Audio. It works fine as a private network. However, if I use it for a long time, the receiving end shows this message - "couldn't find source 1 for /ping message" on the screen and there is no sound. Restart SonoBus and it will work normally. On the sending side- same Raspberry Pi 3B , streaming for more than a week is no problem at all.

Attached Test result Ping.

Thank you.
