A 2010 motherboard with 2 x 2011 CPUs (16 core at > 1.6GHz) is weak compared to modern servers. The machine is sufficiently powerful for what it should do. It just doesn’t do that yet, because it crashes.

There is a group of sysadmins in contact with Vikings and taking care of the build farm. I’d rather keep the discussions about how to move forward with our servers there. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
