Problem with webradio


I have a problem with webradio playback. Sometimes it is okay, but sometimes it suddenly stops playing music when changing between radio stations. Sometimes it does not even start for the first time. Restart of whole Volumio helps in most cases.
I am using newest Volumio with Raspberry Pi Zero W.

volumio@volumio:/var/log$ uname -a
Linux volumio 4.4.9+ #884 Fri May 6 17:25:37 BST 2016 armv6l GNU/Linux
Volumio Version: 2.201

Log extract from /var/log/volumio.log here:
Can anyone help?

Thank you
