I recently installed a new FreeBSD 10 server at home (on my trustly old IBM Thinkpad). After seeing that openjdk8 was out, I thought I would install it from ports and give it a spin.
During installation I received the following kernel warning in my SSH console:
476 Apr 24 06:26:15 beastie devd: Executing 'logger -p kern.emerg 'WARNING: system temperature too high, shutting down soon!'' 477 Apr 24 06:26:15 beastie root: WARNING: system temperature too high, shutting down soon!
sysctl revealed the following:
root@beastie:/usr/ports/java/openjdk8 # sysctl -a | grep temperature hw.acpi.thermal.tz0.temperature: 86.0C hw.acpi.thermal.tz1.temperature: 81.0C
Holy smokes (literally speaking) that is one hot compilation! I quickly shut down the job of course just to make sure I didn’t burn down the machine.
