Last night, after about 13 hours of uptime, the system became unresponsive. All KVM guests were disabled, and the system was pretty quiet . Unfortunately, I was sacked out, so I didn't see anything happen, and nothing unusual was logged. The system _was_ however transcoding an mkv video to mpeg2video, about 1.1 GB in size, but the process wasn't running as root, it was running as user pytivo. After rebooting and disabling all KVM guests, I once again transcoded two mkv videos as user pytivo, and this did not take the system down.
I've now booted with the natty narwhal kernel again: vmlinuz-2.6.37-8-server . While vmlinuz-2.6.37-9-server HAS loaded from the ppa, grub will not utilize it, claiming it is a xen kernel. I have logged a separate bug report on that (688977) . I am currently booted with kernel option "nomodeset" to clean up logging a bit. I'm running vmstat to monitor free memory as well, so with the next system hang, I'll at least have a picture of the final vmstat situation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/688068 Title: lucid system randomly locks up, does not recover -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
