    spontaneous reboots

    I have been running fiesty fawn for some time without any problems until a few weeks ago. I was walking by my pc and noticed that it was rebooting. I though thats weird and did not worry about it. Over the next few days it did it again. So I checked the logs and found that it was an automatic restart that seemed to be related to acron. But I did not use acron or have any events set. So I removed acron and it seemed to be fixed until this morning. I have this in my system log 08/15/2007 06:26:44 AM boosted syslogd 1.4.1#20ubuntu4 restart. After this I have the normal kernel boot stuff until this

    And then there is another reboot. Does this look like a hdd failure? My hdd is only about 6 months old. Of course it never does it when I am in front of it. I would have to say that in the past 7 yrs of running linux this actually my first "crazy problem".

    It almost looks like the file system is getting corrupted. I don't know if a bad hard drive would cause a total reboot but it does look like it might be failing. In any case I would be backing everything up to be on the safe side.

      Thanks. Is there a file system log? Of course this would be a 320 gig drive with 150 gigs of data. Time to break out all my spare smaller drives.

        Oh, oh ... if this were my machine, I'd run a full-fledged file system check on all partitions in questions (man fsck.ext3).

          Ran the check on both partitions. root was 3.5% non-contiguous. home was 5% non-contiguous. I had to force the check because it said they were both clean. I also told it to optimize with -D option. I did not get any other messages.

            Re: spontaneous reboots

            Do you have a reasonable amount of unused space (percentage available) in the partitions with the fsck issues? Linux filesystems do not like to be pushed too full.

              my root partition is 21 gig with 4.6 gig used. my home partition is 278 gig and it had 130 gig of used space. I am in process of moving data for safe keeping.

                Wow, you're in good shape then. You could reduce that root partition down to 7 or 8 GB, if you want.

                Obviously, the rebooting issue is not due to running out of filesystem capacity. :P

                  Thought I made a post about the -c option of fsck.ext3. It checks for bad blocks, which could take a while on a large drive.

                    That's an interesting one

                    To get an idea of what's going wrong, I'd write a little "pseudo daemon" script to the effect that every couple of seconds the output from "top" and "ps aux" is going to be dumped to a file ... you get the idea (and feel free to send me a mail (!) if you need me to code this for you).
