My WRAP has hung 10 times since about 22 April. I'm running 1.11 software,
with a fairly heavy P2P load over a 1200/200 Kbit line. Some of those
hangs came on very hot days, when the temperature was about 35C in my
server room. The last two happened with an ambient temperature of less
than 30C. I run with the cover off at 12V, and AC is from an UPS.
