VolumIO high CPU - unresponsive


I’m running 10 x Raspberry Pi 3s with Hifiberry DAC+ boards, wired network and 2A PSUs

These are running web radio streams 24/7 but we’re having issues with them appearing to freeze. Playback stops and the web UI wont load. They are normally responsive to ping and I can normally SSH to reboot, but sometimes they need a hard reset. When I can SSH into them, the Volumio process is consuming 50% CPU, compared to 10-20% of the ones acting normally.

Out of the 10, we’re finding 1 or 2 locking up in this way every few days. I did notice that there was a newer version available so I’ve just updated them all, but wondering if anyone had experienced this before?
