E.g buildworld -j8 is likely to crash the box. No messages, just a sudden freeze, no backtrace or panic, and then reboot. If load is less heavy, e.g. fewer processes and some idle time, the problem doesn't seem to appear. I'm happy to do any further testing, if suggested. -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 928 8233 Fax: +44 (0)117 929 4423Received on Mon Jul 27 2009 - 19:04:36 UTC
