I have (quiet) the same issue twice in 2 days (on karmic) But I am not using ext4 (only ext3 and jfs)
and the first crash I had, it was trackerd the first blocking task : (from kern.log) Apr 19 11:28:43 localhost kernel: [156600.910099] INFO: task trackerd:3486 blocked for more than 120 seconds. (full kern.log on demand) The second time it was cron (but I didn't check if the ran script was IO consuming or not) (from kern.log) Apr 20 14:20:59 localhost kernel: [68160.710147] INFO: task cron:28148 blocked for more than 120 seconds. (log of Apr 20 seems to be polluted by the systReq I misused) No "strange" update the last days, but I enabled a new django site the day before the first crash (in debug mode) => maybe memory whore. For my specific case (may be different than the one reported here) I suspect 2 causes : * hardware failure. * or bad behavior of something in case of (low memory + huge IO activity.) -- "Smbd","kjournald2" and "rsync" blocked for more than 120 seconds while using ext4. https://bugs.launchpad.net/bugs/494476 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
