I have a system showing very similar (and unpredictable) shut off behavior.
I noticed in my logs that motd was getting called via cron just as the system seem to vanish. The next entry in the log was me rebooting the box. In this case, it always happened during inactivity, until this morning. I ran r...@www:~# [ -x /usr/sbin/update-motd ] && /usr/sbin/update-motd 2>/dev/null repeatedly by up arrowing and running as fast as I could. after a few seconds is just powered off, in a flash. It's a 64bit server 9.04 Ubuntu install on a AMD 4800+ system with 4 GB of corsair ram. System has never had any trouble up until now. -- Random system shutdowns during inactivity (Total power off) after upgrade from 8.10 to 9.04 https://bugs.launchpad.net/bugs/376928 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
