MDs "crashing"

[B34N]

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?

Thank you,

The problem didn't repeat itself last night. That's strange because it froze twice on the core over two days after just playing Pandora through a browser for about 45-minutes. I couldn't get any response from the MD interface. I even tried issuing quick reloads and that didn't have any affect. On the NUC MD it froze after a few moments of playing back a video. The only way I could get any response was to do a hard reset.

I'll keep monitoring and try to see if there is any pattern or if the df -h shows anything different if the problem comes up again.

Thank you,

if it freezes again,

connect via ssh, and do

Code: [Select]

$ top

and observe, look for processes taking up 100% or more CPU time. is it X?
