Playback stops when multitasking on power mode

I just purchased my powernode and it seems to be working fine. All files are played from a NAS share where I was able to select multiple tracks from various artists. However I noticed that when I tried to add more music to the queue while it was playing my initial selections, the music stopped. The powernode stops responding as well so the library functions in the Bluesound app don’t work either. The only solution I found was to unplug the powernode and then plug it into the outlet again? It recovered nicely and even remembered the current entries in the queue.

I think the system is just too busy, anyone else see this?
