Temperature and Failure??

[DougMcIntyre]

I recently got my Kickstarter reward board.
 
I ran it up on an Ubuntu 14.04 server system, yesterday everything
seemed to be working fine.

Today, things seem to be a bit wonky.

Ie. I am getting things like..

Jun 18 17:02:46 rock rngd: read error
Jun 18 17:02:46 rock rngd: message repeated 99 times: [ read error]
Jun 18 17:02:46 rock rngd: No entropy sources working, exiting rngd

But then I unplug it and plug it back in

and it looks like it is good again

Jun 18 17:03:13 rock kernel: [86034.052224] cdc_acm 3-1:1.0: ttyACM0: USB ACM device
Jun 18 17:03:17 rock OneRNG: firmware verification passed OK - version=3

and I see it feeding data into rngd..

root     11046  0.0  0.0   8964   600 ?        SN   17:03   0:00 rngd -n 1 -d 1 -p /va
r/lock/LCK..ttyACM0 -r /dev/ttyACM0

But I expect it to be able to feed me lots of data..

rock:~> dd if=/dev/random of=/dev/null bs=1000 count=1
0+1 records in
0+1 records out
78 bytes (78 B) copied, 0.000244668 s, 319 kB/s

Not just 78 bytes before crapping out.

The orange light is on solid, but it is very warm to the touch when I
feel it. If I had to guess, somewhere around 130 degrees F. It is
running outside the server (for now) in a datacenter environment, so
it is much warmer than most everything around it.

Yesterday, I'm sure I was able to get huge blocks of randomness from /dev/random,
but today, I seem to be limited to normal system entropy.

Any advice for further testing?
