El 10/06/2012, a les 0:33, Peter Lothberg va escriure: Now I've got another problem. The TOPS-10 node goes yo-yo: (...) $ It's outside tops10, I guess, and I'm completely lost there. If my braincells starts to work I will rember how to log all the DECnet packets on the -10 side. --P Its fixed now. I'm running the PDP-10's in a virtualbox VM, and I'm using a virtualbox feature that allows to cap the %CPU of the host CPU the VM can use. If I cap it to under 40% the virtual ethernet devices begin to drop packets and the yo-yoing begins. Curiously, TOPS-20 is more resilient and, although I see its ethernet dropping as much packets as the TOPS-10 one it does not drop itself from the network... KLH10 does not seem to have an idle loop detection like SIMH does. The Panda TOPS-20 uses some sort of virtual device to make the host aware if it is idling, but the regular TOPS-10 monitor does not, so it's using the 100% of the CPU time of the host virtualbox machine. So if I don't cap it it ends topping one of the cores of the "real" host machine. And the it gets hot :) Jordi Guillaumes i Pons jg at jordi.guillaumes.name HECnet: BITXOV::JGUILLAUMES
