Sorry, haven't checked this thread in a while. Finals and all that. I'm pretty sure nobody's logging into my machine remotely, but I'm not quite sure how I'd check, short of obsessively checking "who". I do have several apache2 instances running:
$ ps -e | grep apache 6069 ? 00:00:00 apache2 25435 ? 00:00:00 apache2 25436 ? 00:00:00 apache2 25437 ? 00:00:00 apache2 25438 ? 00:00:00 apache2 25439 ? 00:00:00 apache2 I'm not sure what they're there for. I don't have BOINC installed, so that's not the problem Oddly enough, some of the "symptoms" of this problem have occurred by themselves recently. For instance, yesterday I suddenly lost my entire filesystem. Every time I attempted to run something that I hadn't already run that session, I got something like: bash: - /usr/bin/perl: input/output error However, I didn't have klogd or ksoftirqd eating up my CPU and disk throughput. I was just suddenly locked out. I can only think that the root partition must have been unmounted somehow, and only the programs that were paged into memory at the time could still be run. I couldn't save anything to the disk either. After some looking around on the net, I saw at least one reference saying that having input/output errors like mine could be indicative of a bad optical or hard drive (most of the bugreports were problems with USB or CD/DVD drives). I've since run smartctl -H and smartctl --all against /dev/sda (my hdd): $ sudo smartctl -H /dev/sda smartctl version 5.38 [i686-pc-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED I'll attach the output of smartctl --all /dev/sda with this message so it doesn't take up lots of room here. The upshot is my hard drive seems healthy. I'm glad it's not faulty hardware, but it also means I still don't know what's wrong. Also, recently I had a similar deadlock, where my CPU usage went through the roof, but in this case after a little bit of me trying to figure out what was going on, Xorg died, and I was left with a blank screen and blinking cursor (the machine was unresponsive). It could be that I have several problems here that are no longer occurring together that I thought were some nastier bug. Thanks in advance for any insight you can provide, ~jdacronym ** Attachment added: "output of 'smartctl --all /dev/sda'" http://launchpadlibrarian.net/27341284/smartctl.all.output -- Hardy: ksoftirqd, dd, klogd use 100% CPU, Disk https://bugs.launchpad.net/bugs/368324 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
