Debian base install, but I have anther boxes that does the same, and it 
is fine.

I am non-subscriptions, and I just did an update yesterday to see if it 
would fix the error. I'll be running a memtest today to see if I can 
find anything.

I hadn't done an update in awhile before that, so I'm leaning towards a 
hardware issue. What do you think?
