My MDs (hybrid core and netboot NUC) have both locked up on me while either playing a movie or Pandora. While the MD portion of the core locked, the rest seemed to keep operating. I was able to see what looked like a Kubuntu error on the core that said something lie "temporary user full". I haven't changed anything and it has been about a month since I updated.
Any thoughts? How do I check the logs to see what the message was?
